The python-vlc python module.

The python module for vlc is named python-vlc.
This python module let you test libvlc API like the VLC video player.
You can install it easily with pip python tool.

C:\Python27\Scripts>pip2.7.exe install python-vlc

Let's see a simple example with this python module:

import os
import sys
import vlc
import pygame
 
def call_vlc(self, player):
 
    player.get_fps()
    player.get_time()
 
if len( sys.argv )< 2 or len( sys.argv )> 3:
        print 'Help: python vlc_001.py your_video.mp4'
else:
    pygame.init()
    screen = pygame.display.set_mode((800,600),pygame.RESIZABLE)
    pygame.display.get_wm_info()
    pygame.display.get_driver()

 
    # get path to movie specified as command line argument
    movie = os.path.expanduser(sys.argv[1])
    # see if movie is accessible
    if not os.access(movie, os.R_OK):
        print('Error: %s wrong read file: ' % movie)
        sys.exit(1)
 
    # make instane of VLC and create reference to movie.
    vlcInstance = vlc.Instance()
    media = vlcInstance.media_new(movie)
 
    # make new instance of vlc player
    player = vlcInstance.media_player_new()
 
    # start with a callback
    em = player.event_manager()
    em.event_attach(vlc.EventType.MediaPlayerTimeChanged, \
        call_vlc, player)
 
    # set pygame window id to vlc player
    win_id = pygame.display.get_wm_info()['window']
    if sys.platform == "win32": # for Windows
        player.set_hwnd(win_id)
 
    # load movie into vlc player instance
    player.set_media(media)
 
    # quit pygame mixer to allow vlc full access to audio device
    pygame.mixer.quit()
 
    # start movie play
    player.play()
 
    while player.get_state() != vlc.State.Ended:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit(2)

The base of this python script is to make an instance of vlc and put into the pygame display.
Another simple example:

The numba python module - part 002 .

Today I tested how fast is jit from numba python and fibonacci math function.
You will see strange output I got for some values.
First example:

import numba
from numba import jit
from timeit import default_timer as timer

def fibonacci(n):
    a, b = 1, 1
    for i in range(n):
        a, b = a+b, a
    return a
fibonacci_jit = jit(fibonacci)

start = timer()
fibonacci(100)
duration = timer() - start

startnext = timer()
fibonacci_jit(100)
durationnext = timer() - startnext

print(duration, durationnext)

The result of this run is:

C:\Python27>python numba_test_003.py

(1.5074824049540363e-05, 0.1847134227837042)

As you can see the fibonacci function is not very fast.
The jit - just-in-time compile is very fast.
Let's see if the python source code may slow down.
Let's see the new source code with jit will not work well:

import numba
from numba import jit
from timeit import default_timer as timer

def fibonacci(n):
    a, b = 1, 1
    for i in range(n):
        a, b = a+b, a
    return a
fibonacci_jit = jit(fibonacci)

start = timer()
print fibonacci(100)
duration = timer() - start

startnext = timer()
print fibonacci_jit(100)
durationnext = timer() - startnext

print(duration, durationnext)

The result is this:

C:\Python27>python numba_test_003.py

1445263496
(0.0007348174871807866, 0.17523103771560608)

The result for value 100 is not the same: 927372692193078999176 and 1445263496.
The first problem is:
The problem is that numba can't intuit the type of lookup. If you put a print nb.typeof(lookup) in your method, you'll see that numba is treating it as an object, which is slow.
The second problem is the output but can be from the same reason.
I test with value 5 and the result is :

The numba python module - part 001 .

Today I tested the numba python module.
This python module allows us to speed up applications with high-performance functions written directly in Python.
The numba python module works by generating optimized machine code using the LLVM compiler infrastructure at import time, runtime, or statically.
The code can be just-in-time compiled to native machine instructions, similar in performance to C, C++ and Fortran.
For the installation I used the pip tool:

C:\Python27>cd Scripts

C:\Python27\Scripts>pip install numba
Collecting numba
  Downloading numba-0.35.0-cp27-cp27m-win32.whl (1.4MB)

C:\Python27\Scripts>pip install numpy
Requirement already satisfied: numpy in c:\python27\lib\site-packages

The example test from official website working well:
The example source code is:

from numba import jit
from numpy import arange

# jit decorator tells Numba to compile this function.
# The argument types will be inferred by Numba when function is called.
@jit
def sum2d(arr):
    M, N = arr.shape
    result = 0.0
    for i in range(M):
        for j in range(N):
            result += arr[i,j]
    return result

a = arange(9).reshape(3,3)
print(sum2d(a))

The result of this run python script is:

C:\Python27>python.exe numba_test_001.py
36.0

Another example using just-in-time compile is used with Numba’s jit function:

import numba
from numba import jit

def fibonacci(n):
    a, b = 1, 1
    for i in range(n):
        a, b = a+b, a
    return a

print fibonacci(10)

fibonacci_jit = jit(fibonacci)
print fibonacci_jit(14)

Also, you can use jit is as a decorator:

@jit
def fibonacci_jit(n):
    a, b = 1, 1
    for i in range(n):
        a, b = a+b, a

    return a

Numba is a complex python module because use compiling.
First, compiling takes time, but will work especially for small functions.
The Numba python module tries to do its best by caching compilation as much as possible though.
Another note: not all code is compiled equally.

YARA another python module - part 002 .

This is another part of YARA python tutorial and the goal of this part is to install the Yara modules.
This is another python module about Yara named yara-python from VirusTotal.
The last tutorial uses the Yara python module.
The YARA modules provide extending features to allow us to define data structures and functions which can be used in your rules to express more complex conditions.
You can also write your own modules.
Some known modules used by YARA are:

• PE
• ELF
• Cuckoo
• Magic
• Hash
• Math

First, you need to install or reinstall YARA to the last version:

>>> yara.__version__
'3.6.3'

The Cuckoo module enables you to create YARA rules based on behavioral information generated by a Cuckoo sandbox.

C:\Python27\Scripts>pip install yara-python

requests-2.13.0 sflock-0.2.16 sqlalchemy-1.0.8 tlslite-ng-0.6.0 unicorn-1.0.1 wakeonlan-0.2.2

Let's test this python module:

>>> import cuckoo
>>> from cuckoo import *
>>> dir(cuckoo)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__',

 'auxiliary', 'common', 'compat', 'core', 'machinery', 'misc', 'plugins', 'processing', 

'reporting', 'signatures', 'web']

Let's test some yara modules:

>>> import yara
>>> rule = yara.compile(source='import \"pe\"')
>>> rule = yara.compile(source='import \"elf\"')
>>> rule = yara.compile(source='import \"cuckoo\"')
>>> rule = yara.compile(source='import \"math\"')

I could not use the YARA modules: hash and magic.
I will solve this problem in the future.
You can also write your own modules ( see this webpage ).

The beauty of Python: subprocess module - part 004 .

This series of python tutorials that we started at the beginning of this blog and called "The beauty of Python" is part of the series of tutorials aimed at the simplicity and beauty of the Python programming language.
The main goal for us is how to use this programming language in everyday life with different tasks.
Today I will come up with examples to cover this goal and show you how to use the subprocess python module.

• using the PowerShell with python :

>>> import subprocess
>>> process=subprocess.Popen(["powershell","Get-Childitem C:\\Windows\\*.log"],stdout=subprocess.PIPE);
>>> result=process.communicate()[0]
>>> print result

• get and print the hostname :

>>> print subprocess.check_output("hostname")

• print the output of ping command :

>>> print subprocess.check_output("ping localhost", shell=True)

• print the output of dir command :

>>> cmd = 'dir *'
>>> supcmd = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> print supcmd.communicate()[0]

• run the python script like python shell :

>>> import sys
>>> import subprocess
>>> pid = subprocess.Popen([sys.executable, "calc.py"])

Using pip into shell to install and use pymunk.

The tutorial for today will show how to use pip into the python shell to install a python package.
The first step is shown in the next image:

The Google Cloud SDK - part 002 .

The next part of my tutorials about the Google Cloud SDK comes with some info about the project.
As you know I used the default sample app engine hello word standard application.
The goal is to understand how it works by working with Google's documentation and examples.
Into this project folder we have this files:

08/17/2017  11:12 PM                98 app.yaml
08/17/2017  11:12 PM               854 main.py
08/17/2017  11:12 PM               817 main_test.py

Let's see what these files contain:
First is app.yaml and come with:

runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /.*
  script: main.app

The next is main.py file:

import webapp2


class MainPage(webapp2.RequestHandler):
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write('Hello, World!')


app = webapp2.WSGIApplication([
    ('/', MainPage),
], debug=True)

The last from this folder is main_test.py :

import webtest

import main


def test_get():
    app = webtest.TestApp(main.app)

    response = app.get('/')

    assert response.status_int == 200
    assert response.body == 'Hello, World!'

The app.yaml file is used to configure your App Engine application's settings of the project.
You can have many application-level configuration files (dispatch.yaml, cron.yaml, index.yaml, and queue.yaml).
This all type of configuration files are included in the top level app directory ( in this case: hello_world).
Let's see some common gcloud commands:

• gcloud app deploy  --project XXXXXX - deploy your project;
• gcloud app browse - show your project running into your browser;
• gcloud components list - show all available components;
• gcloud components update - update all gcloud components;
• gcloud projects list --limit=10 - show all projects with a limit number;

Let's test some changes:
First, change the text from main.py file with something else:

self.response.write('Hello, World!')

Now use this commands:

C:\Python27\python-docs-samples\appengine\standard\hello_world>gcloud app deploy
C:\Python27\python-docs-samples\appengine\standard\hello_world>gcloud app browse

The result is shown in your browser.
You can read about this files into google documentation page - here.
Also some gcloud commands and reference you can read here.

The Google Cloud SDK - part 001 .

This tutorial will cover this steps into development with Google Cloud SDK and Python version 2.7:

• install the Google Cloud SDK on the computer;
• make settings online for your Google project to use Google Cloud SDK;
• run the online project of Google Cloud SDK;
• make setting into your computer to run the local project ;

First, you need to download the Google Cloud SDK and run it.


After GUI install a window command will ask you to set the default project for your work.

Welcome to the Google Cloud SDK! Run "gcloud -h" to get the list of available commands.
---
Welcome! This command will take you through the configuration of gcloud.

Your current configuration has been set to: [default]

You can skip diagnostics next time by using the following flag:
  gcloud init --skip-diagnostics

Network diagnostic detects and fixes local network connection issues.
Checking network connection...done.
Reachability Check passed.
Network diagnostic (1/1 checks) passed.

You must log in to continue. Would you like to log in (Y/n)?  Y
...

The next step is to start online to deploying a Hello World app with: Deploy a Hello World app:

This will start an online tutorial into the right area of the screen with all commands and steps for your Google Cloud SDK online project.
Follow this steps and in the end will see how the online Google Cloud SDK project will show: Hello, World! into your browser.
The next step is to make a local project and run it.
You can use the python docs sample from GoogleCloudPlatform but is not the same with the online example.
To download the GoogleCloudPlatform sample use git command:

C:\Python27>git clone https://github.com/GoogleCloudPlatform/python-docs-samples

You can stream logs from the command line by running:
  $ gcloud app logs tail -s default

To view your application in the web browser run:
  $ gcloud app browse

C:\Python27\python-docs-samples\appengine\standard\hello_world>gcloud app browse
Opening [https://XXXXXX.appspot.com] in a new tab in your default browser.

C:\Python27\python-docs-samples\appengine\standard\hello_world>

This will start your application with the text - Hello, World! into your browser address bar with this web address: XXXXXX.appspot.com.

The DreamPie - interactive shell .

The DreamPie was designed to bring you a great interactive shell Python experience.
There are two ways to install the DreamPie:

• cloning the git repository;
• downloading a release.

You can read about installation and download here.
To run it just try the dreampie.exe with your python shell, I used with my python 2.7 version:

C:\DreamPie>dreampie.exe --hide-console-window c:\Python27\python.exe

Let's see one screenshot of this running command:

Also, I tested with Python 3.6.2 and works well.
The main window is divided into the history box and the code box.
The history box lets you view previous commands and their output.
The code box for writing your code.
Some keys I used:

• Ctr+Enter - run the code;
• Ctr+up / down arrow - adds the previous / next source code;
• Ctr+Space - show code completions;
• Ctr+T - open a new tab code;
• Ctr+W - close the tab code;
• Ctr+S - save your work history into HTML file.

You can set your font, colors and many features.
I make the installation into C:\DreamPie folder, and comes with all these folders and files:

C:\DreamPie>tree

The flickrapi python module .

Flickr is one of the most popular photo hosting websites.
The development team let us test the API and with a plenty of opportunities to use Flickr.
Today I tested the flickrapi python module.
I used the python 2.7 version and pip to install it.

C:\>cd Python27

C:\Python27>cd Scripts

C:\Python27\Scripts>pip install flickrapi
Collecting flickrapi
  Downloading flickrapi-2.3-py2-none-any.whl
...
  Running setup.py install for oauthlib ... done
Successfully installed flickrapi-2.3 oauthlib-2.0.2 requests-oauthlib-0.8.0 requests-toolbelt-0.8.0

You need to have/make an API key into Account Settings, see my API key:
Your API keys You have 1 API key registered to this account.
Then you need to know your user_id.
This can be done by asking api online with your username and the result will be something like this: xxxxxxxx@Nxx.
The example I used is from documentation and I change with my API key to test this python module.

>>>import flickrapi
>>>
>>>api_key = u'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
>>>api_secret = u'YYYYYYYYYYYYYYYYYYYYYYY'
>>>
>>>flickr = flickrapi.FlickrAPI(api_key, api_secret)
>>>photos = flickr.photos.search(user_id='xxxxxxxx@Nxx', per_page='10')
>>>sets = flickr.photosets.getList(user_id='xxxxxxxx@Nxx')
>>> dir(sets)

>>> flickr.upload("0001.gif")

>>> print "try show title of my photos and id"
try show title of my photos and id
for child in photos:
  for i in child:
    photo_set = []
    try:
      title = i.attrib['title']
      print title
    except Exception, e:
      print e
    sets = flickr.photos_getAllContexts(photo_id = i.attrib["id"])
    for j in sets:
      if j.tag == "set":
        photo_set.append(j.attrib["id"])
        print photo_set

The result is my photos title and id:

The pysolar - python module.

Today I tested another python module named pysolar with python 2.7 and 3.6.2 versions.
You can read more about this python module here:
Pysolar is a collection of Python libraries for simulating the irradiation of any point on earth by the sun. It includes code for extremely precise ephemeris calculations and more.
Using pip under Windows OS to install this python module:

C:\Python27\Scripts>pip install pysolar
...
Successfully built pysolar
Installing collected packages: pysolar
Successfully installed pysolar-0.7

I try also with python 3.6.2 version:

C:\Python362\Scripts>pip install pysolar
Collecting pysolar
  Using cached pysolar-0.7.tar.gz
Installing collected packages: pysolar
  Running setup.py install for pysolar ... done
Successfully installed pysolar-0.7

Let's start with a simple example to calculate the angle between the sun and a plane tangent to the earth where
you are:

C:\Python362>python.exe
Python 3.6.2 (v3.6.2:5fd33b5, Jul  8 2017, 04:57:36) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from pysolar.solar import *
>>> import datetime
>>> my_data = datetime.datetime.now()
>>> print (my_data)
2017-08-10 18:12:01.997373
>>> get_altitude_fast(47.4616,26.3015,datetime.datetime.now())
-6.393190003993212

Let's try the scattering of light by the atmosphere, though it uses an
atmospheric model based on data taken in the United States:

>>> latitude_deg =47.2741
>>> longitude_deg = 26.185
>>> my_data = datetime.datetime.now()
>>> altitude_deg = get_altitude(latitude_deg, longitude_deg,my_data)
C:\Python362\lib\site-packages\pysolar\time.py:105: UserWarning: I don't know about leap seconds after 2015

Using Flask and Flask-WTF to build websites in Python 2.7 and 3.6.2 - part 002.

This is one update of my old tutorial about Flask and python 2.7 under Linux from here.
The default install of python 2.7 and pip is very simple - read this tutorial.
First, you need to install the Flask python module under Windows 10:

C:\Python27\Scripts>pip install Flask

Running setup.py install for itsdangerous ... done
Successfully installed Flask-0.11.1 Jinja2-2.8 MarkupSafe-0.23 Werkzeug-0.11.11
click-6.6 itsdangerous-0.24

The simple example of the running Flask python module is one script named hello.py:

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":
    app.run()

Using the command to run the script and show the result into your browser:

C:\Python27>python.exe hello.py
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Now the installation of Flask-WTF python module:

C:\Python27\Scripts>pip install Flask-WTF
Collecting Flask-WTF
  Downloading Flask_WTF-0.14.2-py2.py3-none-any.whl
Collecting WTForms (from Flask-WTF)
  Downloading WTForms-2.1.zip (553kB)

Installing collected packages: WTForms, Flask-WTF
  Running setup.py install for WTForms ... done
Successfully installed Flask-WTF-0.14.2 WTForms-2.1

Now I try with Python 3.6.2 with both python modules and works great.

C:\Python362\Scripts>pip3.6.exe install flask
...
Successfully installed Jinja2-2.9.6 MarkupSafe-1.0 Werkzeug-0.12.2 click-6.7 flask-0.12.2 itsdangerous-0.24

The gtts python module.

This python module named gtts will create an mp3 file from spoken text via the Google TTS (Text-to-Speech) API.
The installation of the gtts python module under Windows 10.

C:\Python27\Scripts>pip install gtts
Collecting gtts
  Downloading gTTS-1.2.0.tar.gz
Requirement already satisfied: six in c:\python27\lib\site-packages (from gtts)

Installing collected packages: gtts-token, gtts, urllib3
  Running setup.py install for gtts-token ... done
  Running setup.py install for gtts ... done
  Found existing installation: urllib3 1.22
    Uninstalling urllib3-1.22:
      Successfully uninstalled urllib3-1.22
Successfully installed gtts-1.2.0 gtts-token-1.1.1 urllib3-1.21.1

Let's see a basic example:

from gtts import gTTS
import os
import pygame.mixer
from time import sleep
 
user_text=input("Type your text: ")
 
translate=gTTS(text=user_text ,lang='en')
translate.save('output.wav')

pygame.mixer.init()
path_name=os.path.realpath('output.wav')
real_path=path_name.replace('\\','\\\\')
pygame.mixer.music.load(open(real_path,"rb"))
pygame.mixer.music.play()
while pygame.mixer.music.get_busy():
    sleep(1)

The text will be taken by input into a user_text variable.
You need to type the text into quotes also you will get an error.
The result will be one audio file named output.wav and play it by pygame python module.
This uses the default voices for all languages. I don't find a way to change this voices with python.
