Python 3.7.3 : Using the win32com - part 004.

This is a source code I created a few days ago.

import win32com.client
strComputer = "."
objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator")
objSWbemServices = objWMIService.ConnectServer(strComputer,"root\cimv2")
colItems = objSWbemServices.ExecQuery("Select * from Win32_ProgIDSpecification")
for objItem in colItems:
    print ("Caption: ", objItem.Caption)
    print ("Check ID: ", objItem.CheckID)
    print ("Check Mode: ", objItem.CheckMode)
    print ("Description: ", objItem.Description)
    print ("Name: ", objItem.Name)
    print ("Parent: ", objItem.Parent)
    print ("ProgID: ", objItem.ProgID)
    print ("Software Element ID: ", objItem.SoftwareElementID)
    print ("Software Element State: ", objItem.SoftwareElementState)
    print ("Target Operating System: ", objItem.TargetOperatingSystem)
    print ("Version: ", objItem.Version)

This script uses the win32com python module to show us info about Win32_ProgIDSpecification.
The result is strange and shows like this:

...
Version:  None
Caption:  Addin Class
...

See the full documentation at this link.

Python 3.7.3 : Using the win32com - part 002.

Today I tested the win32com python module with python 3.7.3.
I'll show you two scripts I tested with this python module.

import win32com.client
strComputer = "."
objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator")
objSWbemServices = objWMIService.ConnectServer(strComputer,"root\cimv2")
colItems = objSWbemServices.ExecQuery("Select * from Win32_ClassicCOMClass")
for objItem in colItems:
    print("Component ID: " , objItem.ComponentId)
    print("Description: " , objItem.Description)
    print("Name: " , objItem.Name)

The result is something like this:

Name:  Shell Execute Hardware Event Handler
Component ID:  {FFC9F9AE-E87A-3252-8E25-B22423A40 }
Description:  System.ThreadStaticAttribute
Name:  System.ThreadStaticAttribute
Component ID:  {FFCDB781-D71C-4D10-BD5F-0492EAFFD }
Description:  PSFactoryBuffer
Name:  PSFactoryBuffer
Component ID:  {ffd90217-f7c2-4434-9ee1-6f1b530db }
Description:  XML Feed Moniker
Name:  XML Feed Moniker

Component ID:  {FFE2A43C-56B9-4bf5-9A79-CC6D42856 }
Description:  Windows Photo Viewer Image Verbs
Name:  Windows Photo Viewer Image Verbs

The following example contains this source code:

import win32com.client
strComputer = "."
objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator")
objSWbemServices = objWMIService.ConnectServer(strComputer,"root\cimv2")
colItems = objSWbemServices.ExecQuery("Select * from Win32_ComponentCategory")
for objItem in colItems:
    print("Category ID: " , objItem.CategoryId)
    print("Name: " , objItem.Name)

The result is something like this:

Name:  3D DirectTransform
Category ID:  {F0B7A1A1-9847-11CF-8F20-00805F2CD }
Name:  Active Scripting Engine
Category ID:  {F0B7A1A2-9847-11CF-8F20-00805F2CD }

Python 3.7.3 : Using the pelican python module and GitHub.

This tutorial follows a similar tutorial from the web.
I tested that tutorial to see if it works.
This tutorial is focused on GitHub but can also be used independently on another python platform.
You need a GitHub Pro, your personal account:
With GitHub Pro, your personal account gets unlimited public and private repositories with unlimited collaborators.

In addition to the features available with GitHub Free, private repositories on GitHub Pro include advanced tools and insights:

Unlimited collaborators
GitHub Pages
Wikis
Protected branches
Code owners
Repository insights graphs: Pulse, contributors, traffic, commits, code frequency, network, and forks
Let's start with pip install tool:

C:\Python373>cd Scripts

C:\Python373\Scripts>pip install pelican ghp-import
...
Installing collected packages: unidecode, blinker, feedgenerator, pelican, ghp-import
Successfully installed blinker-1.4 feedgenerator-1.9 ghp-import-0.5.5 pelican-4.0.1
 unidecode-1.0.23

Now you can create a new repository with your name into the GitHub website.
I create a repository named catafest:

C:\Python373\Scripts>git clone https://github.com/catafest/catafest.git blog
Cloning into 'blog'...
warning: You appear to have cloned an empty repository.

C:\Python373\Scripts>cd blog

C:\Python373\Scripts\blog>git checkout -b content
Switched to a new branch 'content'

C:\Python373\Scripts\blog>pelican-quickstart
Welcome to pelican-quickstart v4.0.1.

This script will help you create a new Pelican-based website.

Please answer the following questions so this script can generate the files
needed by Pelican.


> Where do you want to create your new web site? [.] .
> What will be the title of this web site? catafest
> Who will be the author of this web site? Catalin George Festila
> What will be the default language of this web site? [English]
> Do you want to specify a URL prefix? e.g., https://example.com   (Y/n) n
> Do you want to enable article pagination? (Y/n)
> How many articles per page do you want? [10]
> What is your time zone? [Europe/Paris] Europe/Bucharest
> Do you want to generate a tasks.py/Makefile to automate generation and publish
ing? (Y/n) y
> Do you want to upload your website using FTP? (y/N) n
> Do you want to upload your website using SSH? (y/N) n
> Do you want to upload your website using Dropbox? (y/N) n
> Do you want to upload your website using S3? (y/N) n
> Do you want to upload your website using Rackspace Cloud Files? (y/N) n
> Do you want to upload your website using GitHub Pages? (y/N) y
> Is this your personal page (username.github.io)? (y/N) y
Done. Your new project is available at C:\Python373\Scripts\blog

The content of the blog file:

[.]              [..]             [content]        Makefile
[output]         pelicanconf.py   publishconf.py   tasks.py
               4 File(s)          6,496 bytes
               4 Dir(s)  333,558,878,208 bytes free

The quickstart created five files and one new directory:

• Makefile: make command convenience tasks for common operations such as running a development server, building a site and cleaning extraneous build files;
• fabfile.py: A Fabric file that has some of the same types of commands as the Makefile. Fabric is a wonderful code library but for now I recommend skipping the Fabric file because unfortunately Fabric does not yet support Python 3;
• develop_server.sh: shell script for running the development server;
• pelicanconf.py: settings file for your Pelican project. If you are used to earlier versions of Pelican this file was instead named settings.py;
• publishconf.py: another (optional) settings file that can be considered as a "production" settings file when you move past the development phase and want to deploy your site;
• content: location for your markup files, which should be stored under pages and posts directories

Now we can use the local Git repo, commit the changes, and push the local changes to the remote repo hosted on GitHub:

C:\Python373\Scripts\blog>git add .
warning: LF will be replaced by CRLF in Makefile.

This can be fixed with:

git config core.autocrlf true

Check the first commit:

C:\Python373\Scripts\blog>git commit -m "first commit"

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'catal_000@catafest.(none)')

Add the mail and name to your git settings:

C:\Python373\Scripts\blog>git config --global user.email "catafest@yahoo.com"
C:\Python373\Scripts\blog>git config --global user.name "catafest"

Use the git for the first commit

I do not want to extend this tutorial, but I can tell you that this python module is very versatile.

Python 3.7.3 : Using the win32com - part 001.

The tutorial is about win32com python module using the python 3.7.3.
First exameple is simple:

import sys
import win32com.client
from win32com.client import constants

speaker = win32com.client.Dispatch("SAPI.SpVoice")
print ("Type word or phrase, then enter.")
while 1:
      text_to_say = input("> ")
      speaker.Speak(text_to_say)

Let's run it.
The Microsoft Speech SDK to speak what you type in from the keyboard.

C:\Python373>python.exe speak_001.py
Type word or phrase, then enter.
> this is a test

The next example is more complex and uses speech recognition to create outputs.
You can change this example to execute tasks.

# This is a sample code for speech recognition using the MS Speech API

from win32com.client import constants
import win32com.client
import pythoncom
 
""" 
You will see a voice say: Started successfully
The you need to start the speech recognition tool.
After running this, then saying "One", "Two", "Three" or "Four" should
display "You said One" etc on the console.
"""
 
class SpeechRecognition:
    """ Initialize the speech recognition with the passed in list of words """
    def __init__(self, wordsToAdd):

        # For text-to-speech
        self.speaker = win32com.client.Dispatch("SAPI.SpVoice")

        # For speech recognition - first create a listener
        self.listener = win32com.client.Dispatch("SAPI.SpSharedRecognizer")

        # Then a recognition context
        self.context = self.listener.CreateRecoContext()

        # which has an associated grammar
        self.grammar = self.context.CreateGrammar()

        # Do not allow free word recognition - only command and control
        # recognizing the words in the grammar only
        self.grammar.DictationSetState(0)

        # Create a new rule for the grammar, that is top level (so it begins
        # a recognition) and dynamic (ie we can change it at runtime)
        self.wordsRule = self.grammar.Rules.Add("wordsRule",
                        constants.SRATopLevel + constants.SRADynamic, 0)

        # Set the wordsRule to be active
        self.grammar.Rules.Commit()
        self.grammar.CmdSetRuleState("wordsRule", 1)

        # Commit the changes to the grammar

Python 3.7.3 : Use the tweepy to deal with twitter api - part 002.

The tutorial for today is about with python 3.7.3
The development team comes with this intro:
An easy-to-use Python library for accessing the Twitter API.
You need to have an application on twitter with tokens and key, see here.
The first step is to install this python module:

C:\Python373\Scripts>pip install tweepy
...
Successfully built PySocks
Installing collected packages: PySocks, tweepy
Successfully installed PySocks-1.6.8 tweepy-3.7.0

This is the source code I used.
Is very simple to understand:

import tweepy

# set the keys strings
consumer_key = ''
consumer_secret = ''
access_token = ''
access_token_secret = ''

# get  the keys 
input("consumer_key :")
input("consumer_secret :")
input("access_token :")
input("access_token_secret :")
print("--------")

# authentification and get data 
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth)
user = api.me()
print (user.name)
user = api.me()
print(user.name)
print(user.location)
search = input("search :")
numberOfTweets = int(input("number of tweets :"))
phrase = input("response phrase :")
for follower in tweepy.Cursor(api.followers).items():
    try:
        follower.follow()
    except tweepy.error.TweepError:
        pass

print("Followed everyone that is following " + user.name)
for tweet in tweepy.Cursor(api.search, search).items(numberOfTweets):
    try:
    #Reply
        print('\nTweet by: @' + tweet.user.screen_name)
        print('ID: @' + str(tweet.user.id))
        tweetId = tweet.user.id
        username = tweet.user.screen_name
        api.update_status("@" + username + " " + phrase, in_reply_to_status_id = tweetId)
        print ("Replied with " + phrase)
    except tweepy.TweepError as e:
        print(e.reason)
    except StopIteration:
        break

for tweet in tweepy.Cursor(api.search, search).items(numberOfTweets):
    try:
        #Reply
        tweet.favorite()
        print('Favorited the tweet') 
        #Retweet
        tweet.retweet()
        print('Retweeted the tweet')   
        #Follow
        tweet.user.follow()
        print('Followed the user')        
    except tweepy.TweepError as e:
        print(e.reason)
    except StopIteration:
        break

The result is this:

C:\Python373>python.exe tweepy_001.py
catafest
catafest
Romania, Suceava, Falticeni
search :Catalin
number of tweets :1
response phrase :Festila
Followed everyone that is following catafest

Tweet by: @rumeys1a
ID: @1103384469703196673
Replied with Festila
Favorited the tweet
Retweeted the tweet
Followed the user

You can see what are the technical follow limits for twitter here.

Python 3.7.3 : The google-cloud-vision python module - part 002.

I used Windows 8.1 and python 3.7.3 version.
The first step is to install the python module.

C:\Python373\Scripts>pip install --upgrade google-cloud-vision

You can see another tutorial about this python module here.
Let's test the python module.

C:\Python373>python
Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD6
4)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from google.cloud import vision
>>> from google.cloud.vision import types
>>> from PIL import Image, ImageDraw

You need to have billing enabled for your Google Cloud Platform project.
Evaluated prices can vary and Google gives us this online calculator, or let us test with a FREE account with 300$.
To change the billing account go to the Google Cloud Platform Console.
Open the console left side menu and select Billing.
If you have more than one billing account then you need to solve this issue, see this webpage.
The Cloud Vision API integrates vision features, like: including image labeling, face, logo, and landmark detection, optical character recognition (OCR), and detection of explicit content, into applications.
You need to set the authentification for your google account and your project, see this page.
The next step is to instantiate a client:

client = vision.ImageAnnotatorClient()

Google provides this tutorial with the same steps as into this tutorial.
You can test and read more about Google Vision on the official page.

Python 3.7.3 : Using the cognitive face detection from Azure Microsoft .

The Microsoft Azure comes with this free feature named Computer Vision:
This API key is currently active
7 days remaining
Distill actionable information from images
5,000 transactions, 20 per minute.

You can test with the cognitive_face python module from GitHub.
Another good example of extract printed text can be found at docs.microsoft.com.
Let's install it:

C:\Python373\Scripts>pip install cognitive_face
...
Installing collected packages: cognitive-face
Successfully installed cognitive-face-1.4.2

Now a simple intro using the dir:

C:\Python373>python.exe
Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD6

Type "help", "copyright", "credits" or "license" for more information.
>>> import cognitive_face as CF
>>> dir(CF)

_group', 'large_person_group_person', 'large_person_group_person_face', 'person'
, 'person_group', 'util']

For detections you need to use the face with detect:

import cognitive_face as CF
# Replace with your valid Subscription Key here.
KEY = '111111111111'  
CF.Key.set(KEY)
# Replace with your regional Base URL based by 
# https://azure.microsoft.com/en-us/try/cognitive-services/my-apis/?apiSlug=computer-vision

BASE_URL = 'https://westcentralus.api.cognitive.microsoft.com/vision/v2.0'  
CF.BaseUrl.set(BASE_URL)

img_url = 'https://previews.123rf.com/images/boarding1now/boarding1now150

result = CF.face.detect(img_url)
print (result)

img_url = 'https://raw.githubusercontent.com/Microsoft/Cognitive-Face-

result2 = CF.face.detect(img_url)
print (result2)

The result of this running code is:

C:\Python373>python.exe face_cognitive_001.py

If you take a look at the images and results will see how this works.

Python 3.7.3 : Try Ethereum with web3.

Today I tested the web3 python module.
This is the Ethereum python module.
More about this python module can be found here.
Ethereum programming has a large area of development.
For transaction you can use:
from web3 import Web3, HTTPProvider, IPCProvider, WebsocketProvider
I tested with an account from infura.io.

>>> from web3 import Web3, HTTPProvider, IPCProvider, WebsocketProvider
>>> w3 = Web3(HTTPProvider('ropsten.infura.io/v3/1f2fb5d1e1be4c11acdbbb07a2e06a1

Python 3.7.3 : Fix kivy python module installation.

Kivy is a multi-platform GUI development library for Python, running on Windows, Mac, Linux, Android, and iOS.
Today I tested kivy python module with python version 3.7.3 and I got some errors but I fixed.
I started with the default installation using the pip tool.

C:\Python373>cd Scripts
C:\Python373\Scripts>pip install kivy
...
Installing collected packages: docutils, pygments, Kivy-Garden, kivy
...
Successfully installed kivy-1.10.1

I used a default script to test the kivy python module.
When I tested I got these errors:

I try to see if the install of these python modules are right:

C:\Python373>cd Scripts
C:\Python373\Scripts>pip install pypiwin32
Requirement already satisfied: pypiwin32 in c:\python373\lib\site-packages (223)

If you search on web you will se this is a common error and some users use this solution:

python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2
python -m pip install kivy.deps.glew
python -m pip install kivy.deps.gstreamer

Hope this help you with python programming and kivy interface.

Python 3.7.3 : Get location of International Space Station.

Today I tested the urllib python module with python 3.7.3 and json python module.
The issue was to get the location of International Space Station - Open Notify.
The International Space Station is moving at close to 28,000 km/h so its location changes really fast! Where is it right now?
This is an open source project to provide a simple programming interface for some of NASA’s awesome data.
I do some of the work to take raw data and turn them into APIs related to space and spacecraft.

Python 3.7.3 and memory_profiler python module.

Today I will come up with a simpler and more effective tutorial in python programming.
First, I need to install the psutil python module for the example of this tutorial.

C:\Python373>cd Scripts
C:\Python373\Scripts>pip install psutil

Python memory monitor is very important for debugging application performance and fix bugs.
You can solve this issue is the python module named memory_profiler, see more here.
Let's install this python module with the pip python tool:

C:\Python373\Scripts>pip install memory_profiler

Let's start with a simple python script example:

import psutil

def test_psutil():
 # gives a single float value
 print(psutil.cpu_percent())
 # gives an object with many fields
 print(psutil.virtual_memory())
 # you can convert that object to a dictionary 
 print(dict(psutil.virtual_memory()._asdict()))
if __name__ == '__main__':
 test_psutil()

C:\Python373>python psutil_001.py
0.0
svmem(total=4171108352, available=1153679360, percent=72.3, used=3017428992, fre
e=1153679360)
{'total': 4171108352, 'available': 1153671168, 'percent': 72.3, 'used': 30174371
84, 'free': 1153671168}

The same result can see if you use memory_profiler

C:\Python373>python -m memory_profiler psutil_001.py
100.0
svmem(total=4171108352, available=1149018112, percent=72.5, used=3022090240, fre
e=1149018112)
{'total': 4171108352, 'available': 1149087744, 'percent': 72.5, 'used': 30220206
08, 'free': 1149087744}

Let's decorate python source code with @profile annotation to have a good output.

import psutil
@profile

Sure, this error tells us the decorate not working in the default way.

C:\Python373>python psutil_001.py
Traceback (most recent call last):
  File "psutil_001.py", line 2, in 
    @profile
NameError: name 'profile' is not defined

In this case, the decorate profile works great with the python module and give us all the information we need:
C:\Python373>python -m memory_profiler psutil_001.py

Let's test with another python script named 001.py :

from memory_profiler import profile

@profile(precision=4)
def test():
    a = 0
    a = a + 1

if __name__ == "__main__":
    test()

The result with precision=4 is this:

C:\Python373>python -m memory_profiler 001.py
Filename: 001.py

Line #    Mem usage    Increment   Line Contents
================================================
     3  15.3945 MiB  15.3945 MiB   @profile(precision=4)

     5  15.3945 MiB   0.0000 MiB       a = 0
     6  15.3945 MiB   0.0000 MiB       a = a + 1

If we change the precision=1 then this is the result:

C:\Python373>python -m memory_profiler 002.py
Filename: 002.py

Line #    Mem usage    Increment   Line Contents
================================================
     3     15.4 MiB     15.4 MiB   @profile(precision=1)

     5     15.4 MiB      0.0 MiB       a = 0
     6     15.4 MiB      0.0 MiB       a = a + 1
