The svgwrite python module - part 001.

The svgwrite python module is a tool by Manfred Moitzi.
To install this python module use Python 3.4 version.
Then you need to install svgwrite with pip3.4:
C:\Python34\Scripts>pip3.4.exe install svgwrite
Collecting svgwrite
  Downloading svgwrite-1.1.6.tar.gz (109kB)
    100% |################################| 110kB 354kB/s
Also this svgwrite is the only module that needs to be imported and then you can deal with this module.
See this simple example:
import svgwrite
from svgwrite import *
#this will work with svgwrite
svg_doc = svgwrite.Drawing(filename = "test-svgwrite.svg",\
                                size = ("30px", "30px"))\
svg_doc.add(svg_doc.rect(insert = (0, 0),\
                                   size = ("20px", "20px"),\
                                   stroke_width = "1",\
                                   stroke = "green",\
                                   fill = "rgb(255,255,0)"))\
print(svg_doc.tostring())
svg_doc.save()
The result of this python script is this SVG file.

If you use the dir() then you can see more about this python module:
>>> dir(svgwrite)
['AUTHOR_EMAIL', 'AUTHOR_NAME', 'CYEAR', 'Drawing', 'Hz', 'Unit', 'VERSION', '__
builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__p
ackage__', '__path__', '__spec__', 'animate', 'base', 'cm', 'container', 'data',
 'deg', 'drawing', 'elementfactory', 'em', 'etree', 'ex', 'filters', 'grad', 'gr
adients', 'image', 'inch', 'kHz', 'masking', 'mixins', 'mm', 'params', 'path', '
pattern', 'pc', 'percent', 'pt', 'px', 'rad', 'rgb', 'shapes', 'text', 'utils',
'validator2', 'version']
For example you can add some text:
svg_doc.add(svg_document.text("This add new svg text",\
                                   insert = (10, 10)))

The new Python 2.7.11rc1.

The next release in the 2.7.x series is now available with the version 2.7.11.rc.1 .
This can be download it from here.
Come with source release, installer for Windows, Mac OS X 10.6 and later.
I don't use linux instalation, just on Windows 10 - 64 MSI installer.
The changes of this version can be see here.
First I saw this python version will change my old python 2.7 version.

Also I check to compile all python scripts and module.
With installed Python 2.7 I check if is all ok.

Some python modules has problems with update...

  Failed building wheel for pycuda
Note:
I think the python has some problems with keep and clean correct modules under pip.
Also I guest can be done with few rows of python scripts but also this can be done by default by python installation.

WinPython - news and old stuff.

First good news: the team tells us about the WinPython will come with new release of WinPython.
This will be 3.4.3.7 version of WinPython and this will be great for most of users.
I love this portable python because first is easy to use and can easy test my python scripts.
One goal of this portable python it's the demos. I found some great demos with PyQt4 and networkx.

Also you can use Spyder to make your python scripts.
It's a free open-source development environment for the Python programming language.
This visual interface similar to MATLAB where you can run commands, edit and debug programs, check the values of variables and the definitions of functions, etc.
If you just getting started with Python then just take a look at google.com/edu/python.
The WinPython Control Panel allows to register your WinPython distribution to Windows with Advanced - Register distribution ...:
...and this allow you to:
  • associate file extensions .py, .pyc and .pyo to Python interpreter
  • register Python icons in Windows explorer
  • add context menu entries Edit with IDLE and Edit with Spyder for .py files
  • register WinPython as a standard Python distribution in the registry (the same way as the standard Python Windows installers will do)
Also you can use Jupyter Notebook web application.
This allow you to:
The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text. Uses include: data cleaning and transformation, numerical simulation, statistical modeling, machine learning and much more.

Testing the SymPy python module with Python 3.4.1 .

SymPy is a Python library for symbolic mathematics.
This module is a computer algebra system (CAS) written in the Python programming language.
A large can be found on this blog aggregator at planet.sympy.org.
First, You need to install it using pip3.4.

The most common printers available in SymPy are:
  • str
  • repr
  • ASCII pretty printer
  • Unicode pretty printer
  • LaTeX
  • MathML
  • Dot
Let's test it this first example:

The last version 1.9.2 of python module can solve instalation over python from sourceforge.net -projects.
This link from Numerical Python module come with exe file over python versions: 3.4 , 3.3 and 2.7.
I test the 3.4 version - 32 bits but I got this great error:
>>> import numpy
Traceback (most recent call last):
File "", line 1, in 
File "C:\Python34\lib\site-packages\numpy\__init__.py", line 170, in 
from . import add_newdocs
File "C:\Python34\lib\site-packages\numpy\add_newdocs.py", line 13, in 
from numpy.lib import add_newdoc
File "C:\Python34\lib\site-packages\numpy\lib\__init__.py", line 8, in 
from .type_check import *
File "C:\Python34\lib\site-packages\numpy\lib\type_check.py", line 11, in 
import numpy.core.numeric as _nx
File "C:\Python34\lib\site-packages\numpy\core\__init__.py", line 6, in 
from . import multiarray
ImportError: DLL load failed: %1 is not a valid Win32 application.
How to fix this:
Also the pip3.4 don't want to install the numpy python module just if you use this link.
You can do this with :
C:\Python34\Scripts>pip3.4.exe install --upgrade wheel
Requirement already up-to-date: wheel in c:\python34\lib\site-packages
C:\Python34\Scripts>pip3.4.exe install "C:\Users\...\Downloads\numpy-1.9.2+m
kl-cp34-none-win_amd64.whl"
After that you can import the numpy module 

PySide - Introduction - part 002.

First, PySide itself is licensed under LGPLv2.1, most of the examples are licensed under GPLv2.
After importing PySide then you can see all PySide python submodule:
>>> import PySide
>>> from PySide import *
>>> dir(PySide)
['QtCore', 'QtGui', 'QtNetwork', 'QtOpenGL', 'QtScript', 'QtSql', 'QtSvg', 'QtTe
st', 'QtWebKit', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '
__package__', '__path__', '__version__', '__version_info__', '_setupQtDirectorie
s', '_utils']
Also this can help you to see all about Qt components and versions using by PySide:
Let's how can do it:
# prints PySide version
>>> print PySide.__version__
1.2.2
# gets a tuple with each version component
>>> print PySide.__version_info__
(1, 2, 2, 'final', 0)
# prints the Qt version used to compile PySide
>>> print PySide.QtCore.__version__
4.8.5
# gets a tuple with each version components of Qt used to compile PySide
>>> print PySide.QtCore.__version_info__
(4, 8, 5)
Something about PySide submodules:
QtCore - core non-GUI functionality;
QtGui - extends QtCore with GUI functionality;
QtNetwork - offers classes that allow you to write TCP/IP clients and servers;
QtOpenGL - offers classes that make it easy to use OpenGL in Qt applications;
QtScript - provides classes for making Qt applications scriptable;
QtSql - helps you provide seamless database integration to your Qt applications;
QtSvg - provides classes for displaying the contents of SVG files;
QtWebkit - provides a Web browser engine;
The QtTest submodule can be used to test your PySide script code.
The structure PySide application can be see under my first tutorial.
About this PySide application most of this can be created with classes
To make one GUI ( ) just import QtGUI with your class ...
This source code can be used also you can get some errors:
>>> import sys
...
>>> from PySide import QtGui
...
>>> app = QtGui.QApplication(sys.argv)
You need sys python module also the application can have this option : sys.argv .
You can searching and used all your widgets.
For example :
>>> import sys
>>> import PySide
>>> from PySide import *
>>> myapp = QtGui.QApplication(sys.argv)
>>> mywidgets = QtGui.QWidget()
>>> mywidgets.show()
The title of your application will be python.
You can set this title bellow show method , with :
mywidgets.setWindowTitle('my app title ')
About my class Example from pyside-introduction-part-001 then I will tell you how to make one simple class example.
First I used this class named Example with this methods:
class Example(QtGui.QWidget):
...
#defaul init class method 
__init__(self)
...
#make and show the window application
initUI(self)
...
#my method to put the window to the desktop screen
center(self)
...
#method to deal with events and also close the application
closeEvent(self, event)
...
Into __init___ I used super() method.
The main reason I used this it's :
-super() method lets you avoid referring to the base class explicitly and let you to use multiple inheritance.
The main function come with some source code:
Make the application :
app = QtGui.QApplication(sys.argv)
and also put my widgets under this with this python code:
ex = Example()
About events I will make another tutorial ...

The new release Python 3.5.0a4 - tutorial.

I install the Windows amd64 web-based installer. This allow me to use the windows gui to make all settings.
You also need some administrator privileges for C Runtime ...

Some notes about this installation process:
  • If you have previously installed Python 3.5.0a1, you may need to manually uninstall it.
  • If installing Python 3.5.0a4 as a non-privileged user, you may need to escalate to administrator privileges to install an update to your C runtime libraries.
  • Python 3.5 now has an embeddable installer designed to be run as part of a larger application's installer for apps using or extending Python.There is now a third type of Windows installer for Python 3.5.
You can find your python files under \AppData\Local\Programs\Python\Python35.
The Python35 have python.exe, see:
Python 3.5.0a4 (v3.5.0a4:413e0e0004f4, Apr 19 2015, 18:01:47) [MSC v.1900 64 bit

Using facepy to deal with facebook .

This python module allow you to get some data from facebook using Facebook’s Graph API.
The development team tell us:
Facepy can do more than reading your latest posts and posting photographs of parrots, but you’ll have to read the documentation to find out how.
You can use pip to install this module ( pip2.7 or pip3.4):
pip install facepy
The python script is simple :

...\Python34>cd Scripts

Install PyOpenGL with pip with wheel and WHL file .

This is a old tutorial I wrote about how to install python on windows 8.1 with distribute, pip, virtualenv and virtualenvwrapper-powershell.
Now I will show you how to deal with WHL files and pip wheel.
First you need to install pip under your python folder.
I used in this case Python 2.7 version.
The WHL file and wheel is a ZIP-format archive with a specially formatted filename and the .whl extension.
You can use this :
C:\Python27\Scripts>pip2.7 install wheel
Collecting wheel
  Downloading wheel-0.24.0-py2.py3-none-any.whl (63kB)
    100% |################################| 65kB 682kB/s ta 0:00:011

    100% |################################| 1.3MB 952kB/s ta 0:00:01
This will install wheel and update the pip2.7 .
For example, just use next command to install OpenGL python module.
C:\Python27\Scripts>pip2.7 install PyOpenGL

Also pygame whl working with pip2.7.
I download it from pygame website, from here. Download your version of WHL file ( amd64 is for CPU 64 bits) and your python version (cpxx). Now use this command:
C:\Python27\Scripts>pip2.7.exe install "C:\Downloads\pygame-1.9.2a
0-cp27-none-win_amd64.whl"
...
Installing collected packages: pygame
  Found existing installation: pygame 1.9.1
    DEPRECATION: Uninstalling a distutils installed project (pygame) has been de
precated and will be removed in a future version. This is due to the fact that u
ninstalling a distutils project will only partially uninstall the project.
    Uninstalling pygame-1.9.1:
      Successfully uninstalled pygame-1.9.1
