LibreOffice and python scripts.

I try to deal with python scripts under LibreOffice applications.
The full tutorial can be found here: Python and LibreOffice – part 001.
I will come with new tutorials about LibreOffice and python.

The python modules pygobject, pycairo and pygtk under Windows OS.

I used the python version 2.7 32 bits under .
C:\Python27>python
Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22) [MSC v.1500 32 bit (
Intel)] on win32

The issue is to instal PyGTK python module but you can see I got errors.
C:\>cd Python27

C:\Python27>cd script
The system cannot find the path specified.

I install this python modules using registry and this option: Python from another location and I set my python path: C:\Python27\
>>> import gobject
>>> dir(gobject)
['GBoxed', 'GEnum', 'GError', 'GFlags', 'GInterface', 'GObject', 'GObjectMeta',
...
>>> import cairo
>>> dir(cairo)

>>> import pygtk
>>> dir(pygtk)

get_available_versions', '_our_dir', '_pygtk_2_0_dir', '_pygtk_dir_pat', '_pygtk

As you can see this python modules works well.

Noise 2D, 3D, 4D with opensimplex python module.

OpenSimplex noise is an n-dimensional gradient noise function that was developed in order to overcome the patent-related issues surrounding Simplex noise, while continuing to also avoid the visually-significant directional artifacts characteristic of Perlin noise.
Let's start with instalation:
C:\Python27\Scripts>pip install OpenSimplex
Collecting OpenSimplex
Downloading opensimplex-0.2.tar.gz
Installing collected packages: OpenSimplex
Running setup.py install for OpenSimplex ... done
Successfully installed OpenSimplex-0.2

Let's make a image example with noise 2D:
from opensimplex import OpenSimplex
from PIL import Image

height = int(input("Enter in the map height: "))
width = int(input("Enter in the map width: "))

def main():
    simplex = OpenSimplex()
    im = Image.new('L', (width, height))
    for y in range(0, height):
        for x in range(0, width):
            value = simplex.noise2d(x , y )
            color = int((value + 1) * 128)
            im.putpixel((x, y), color)
    im.save('noise2d.png')
    im.show()
if __name__ == '__main__':
    main()

The python-nmap python module fail.

You can read about this python module here.

First let's install this python module.
C:\Python27>cd Scripts

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

I try to run the example source code but not of this example working.
For example I got this:

Python 3.4 and Flask module - part 001.

This is a simple tutorial about how to install Flask python module under python 3.4 .
I think this can also working with any python 3.x versions.
Flask is a microframework for creating web applications.
First you need to install your python 3.4 and then you will get the pip script from here.
About pip you can read more on the pip webpage.
Run the pip install:

python get-pip.py

Go to into your Python folder and start the pip installation of Flask python module.
C:\Python34>cd Scripts
C:\Python34\Scripts>pip install Flask
Downloading/unpacking Flask

This is the first step. The next step is to start the default webpage.
Using python command shell you can test the Flask python module.

>>> from flask import Flask
>>>
>>> app = Flask(__name__)
>>>
>>> @app.route('/')
... def homepage():
... return "Hi there, how ya doin?"
...
>>>
>>> if __name__ == "__main__":
... app.run()
...
* Running on http://127.0.0.1:5000/
127.0.0.1 - - [26/Sep/2014 23:25:01] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [26/Sep/2014 23:25:02] "GET /favicon.ico HTTP/1.1" 404 -


As you can see is running into browser at http://127.0.0.1:5000 .
Let's put this into one python script.
You need to make a new folder called FlaskApp and go to this folder.
Make a new script named app.py with the source code you tested.
Now you can just run the script and all will be working well.
Flask looks for template files inside the templates folder.
Go to the folder FlaskApp and create a folder called templates.
Now, create a file called index.html and fill with you html source code.
To call this index.html you need to add this line of source code ino your script:
from flask import Flask, render_template and
def main():
return render_template('index.html')
Start your python script and you will see the content of your index.html.

OpenGL and OpenCV with python 2.7 - part 004.

Today I will continue the series of graphics processing in OpenGL and OpenCV.
The goal of this tutorial is the download and load into the python script of a youtube video.
To do that we need another two modules python.
First, I download and install the python 2.7.12 32 bit version from the internet.
C:\Python27>python.exe
Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22) [MSC v.1500 32 bit (
Intel)] on win32

First update the pip tool and install numpy python module:
C:\Python27\Scripts>python -m pip install --upgrade pip
Collecting pip

The main reason to have the numpy python module: it is often used with OpenCV python module.
For OpenCV python module installation you need to see my tutorial.
After you install it, test the OpenCV python module:
C:\Python27>python.exe
Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22) [MSC v.1500 32 bit (

>>> print cv2.__version__

Install pafy python module.
This module help you to download video from youtube but you need also the youtube-dl python module.
So let's install the youtube-dl and pafy python modules.
C:\Python27>cd Scripts
C:\Python27\Scripts>pip install youtube-dl
Collecting youtube-dl
Downloading youtube_dl-2016.12.1-py2.py3-none-any.whl (1.5MB)

C:\Python27\Scripts>pip install pafy
Collecting pafy
Downloading pafy-0.5.2-py2.py3-none-any.whl
Installing collected packages: pafy
Successfully installed pafy-0.5.2

I make a simple python script named: get_yt.py.
The source code of this script is simple:
import os
import pafy
# Download the video
video = pafy.new('https://www.youtube.com/watch?v=O5VCjktWVD4')
print "video.title"
print video.title
print "video.rating"
print video.rating
print "video.viewcount, video.author, video.length"
print video.viewcount, video.author, video.length
print "video.duration, video.likes, video.dislikes"
print video.duration, video.likes, video.dislikes
print "video.description"
print video.description
resolution = video.getbestvideo(preftype="mp4")
print "resolution"
print resolution
input_movie = resolution.download(quiet=False)
print "input_movie"
print input_movie
print "delete movie"
os.remove(input_movie)

I used the URL of a video clip from youtube channel of Arden Cho to tested.
If you want to keep the video into your folder just remove the last line from the python script.
The result is this output:
C:\Python27>python.exe get_yt.py
video.title

Python and OAuth2 with Google API.

If you want to do this then is simple to do. The most complex part comes from google settings.
But that can be easy if you make it from a few times.
I used OAuth2 with JSON file to make authentification.
You can see my full tutorial here.
