News: The new python version 3.6.0.a1

I used the Windows x86-64 executable installer to install this version of python.
I set some settings and I start the install aplication.

I read all new changes and PEP 0498.
I take a look to see all python modules:

Please wait a moment while I gather a list of all available modules...

The new formatted string literals are a new kind of string literal, prefixed with 'f' this allow you to add contain replacement fields surrounded by curly braces.
I don't think the add Python start well, maybe need restart:

 >>> import crypt
Traceback (most recent call last):
  File "", line 1, in 
  File "C:\Python36\lib\crypt.py", line 3, in 
    import _crypt
ImportError: No module named '_crypt' 

Some of changes can be see at whatsnew.
You can read more and also download the new python released version 360a1 from here.
Very good work from development team, they make a great job.

News: New PyPy 5.1 released.

New features and bug fixes come with new PyPy 5.1 version.
The PyPy is a very compliant Python interpreter and supports x86 machines on most common operating systems.
Now we have full support for the IBM s390x and good optimizations.
Take a look here.

Testing PyQt4 under Python 3.5.1.

Today I working well with python 3.5.1.
Most of my source code was wrote with python 2.7 and the next step was to using pip3.5 to update and upgrade some python modules.
I try to install PyQt4 with pip3.5 - not working.
So I used the old way: whl file from here.
That was good, most of the scripts was running.
The main problem was OpenGL and that will make errors when you try to use QtOpenGL.
The result of this seam to me the python 3.5.1 it's now without OpenGL features.

The most short source code into Python 3.5.1 .

Just type this :

import antigravity

That will open your browser with one comics from xkcd website.
The antigravity module was added to Python 3.5.1. I'm not sure but seam working also with python 2.7 version.

wmi python module - part 002.

According to MSDN Microsoft the Win32_Process WMI class represents a process on an operating system.
We can see all of the inherited properties of processes:

class Win32_Process : CIM_Process
{
  string   Caption;
  string   CommandLine;
  string   CreationClassName;
  datetime CreationDate;
  string   CSCreationClassName;
  string   CSName;
  string   Description;
  string   ExecutablePath;
  uint16   ExecutionState;
  string   Handle;
  uint32   HandleCount;
  datetime InstallDate;
  uint64   KernelModeTime;
  uint32   MaximumWorkingSetSize;
  uint32   MinimumWorkingSetSize;
  string   Name;
  string   OSCreationClassName;
  string   OSName;
  uint64   OtherOperationCount;
  uint64   OtherTransferCount;
  uint32   PageFaults;
  uint32   PageFileUsage;
  uint32   ParentProcessId;
  uint32   PeakPageFileUsage;
  uint64   PeakVirtualSize;
  uint32   PeakWorkingSetSize;
  uint32   Priority = NULL;
  uint64   PrivatePageCount;
  uint32   ProcessId;
  uint32   QuotaNonPagedPoolUsage;
  uint32   QuotaPagedPoolUsage;
  uint32   QuotaPeakNonPagedPoolUsage;
  uint32   QuotaPeakPagedPoolUsage;
  uint64   ReadOperationCount;
  uint64   ReadTransferCount;
  uint32   SessionId;
  string   Status;
  datetime TerminationDate;
  uint32   ThreadCount;
  uint64   UserModeTime;
  uint64   VirtualSize;
  string   WindowsVersion;
  uint64   WorkingSetSize;
  uint64   WriteOperationCount;
  uint64   WriteTransferCount;
};

Let's make one simple example with wmi python module.

import wmi
c = wmi.WMI()
for process in c.Win32_Process ():
 name = process.Properties_("Name").Value
 pid = process.Properties_('ProcessID').Value
 parent = process.Properties_('ParentProcessId')
 termination = process.Properties_('TerminationDate')
 print (name,' = pid -',pid,'+', parent,'|termination_date-',termination)

And the output of this script it's :

firefox.exe  = pid - 13788 + 2564 |termination_date- None
explorer.exe  = pid - 1048 + 772 |termination_date- None
sublime_text.exe  = pid - 11404 + 2564 |termination_date- None
plugin_host.exe  = pid - 7432 + 11404 |termination_date- None
cmd.exe  = pid - 9568 + 2564 |termination_date- None
conhost.exe  = pid - 14124 + 9568 |termination_date- None
conhost.exe  = pid - 9700 + 11208 |termination_date- None
Taskmgr.exe  = pid - 9424 + 13404 |termination_date- None
WmiPrvSE.exe  = pid - 9764 + 772 |termination_date- None
SpfService64.exe  = pid - 11908 + 684 |termination_date- None
python.exe  = pid - 1308 + 9568 |termination_date- None

wmi python module - part 001.

Named WMI from Windows Management Instrumentation, this python module allow you to use Microsoft’s implementation of Web-Based Enterprise Management ( WBEM ).
Is a set of extensions to the Windows Driver Model AND that provides an operating system interface.
allows you to scripting languages like VBScript to manage Microsoft Windows personal computers and servers, both locally and remotely.
You cand read about this python module here.

C:\Python34\Scripts>pip install  wmi
...
Installing collected packages: wmi
Running setup.py install for wmi
warning: install_data: setup script did not provide a directory for 'readme.
txt' -- installing right in 'C:\Python34'

Cleaning up...

Let try first example :

C:\Python34>python
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 10:45:13) [MSC v.1600 64 bit (AM
D64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import wmi
>>> remote_process = wmi.WMI (computer="home").new ("Win32_Process")
>>> for i in wmi.WMI ().Win32_OperatingSystem ():
...     print (i.Caption)
...
Microsoft Windows 10 Home

Now let's see another example can used by you with wmi python module.
This example let you see your processes.

import wmi
import datetime
c = wmi.WMI()
process_watcher = c.Win32_Process.watch_for("modification")
while True:
  new_process = process_watcher()
  print (new_process.Caption)

I used the python version 3.3.5 and Spyder ( Scientific PYthon Development EnviRonment ) to test the script.
You can change .watch_for method args with: creation, deletion, modification or operation.

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.

C:\Python27>python.exe
Python 2.7.11rc1 (v2.7.11rc1:82dd9545bd93, Nov 21 2015, 23:25:27) [MSC v.1500 64
 bit (AMD64)] on win32

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.

For a short introduction into SymPy python module I will show you the printing features.
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:

C:\Python34>python
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 10:45:13) [MSC v.1600 64 bit (AMD64)] on win32

>>> x,y,z = symbols('x y z')
>>> Integral(sqrt(1+1/x),x)
Integral(sqrt(1 + 1/x), x)
>>> init_session(quiet=True)

 |   /  1 + -  dx
 | \/       x

How to print one matrix :

>>> x, y, z = symbols('x, y, z')
>>> init_session(quiet=True)
Python console for SymPy 0.7.6 (Python 3.4.1-64-bit) (ground types: python)

>>> mat = Matrix([x*y, 1,0,3,-2, sin(z)])
>>> mat
[ x*y  ]
[      ]
[  1   ]
[      ]
[  0   ]
[      ]
[  3   ]
[      ]
[  -2  ]
[      ]
[sin(z)]
>>>

Next example come with this issue: equations can be solved with SymPy python module.

>>> solve(x*x+x+2)
         ___            ___
   1   \/ 7 *I    1   \/ 7 *I
[- - - -------, - - + -------]
   2      2       2      2
>>> solve(Eq(x*x+x+2))
         ___            ___
   1   \/ 7 *I    1   \/ 7 *I
[- - - -------, - - + -------]
   2      2       2      2
>>> solve(Eq(x*x+2*x+4))
        ___           ___
[-1 - \/ 3 *I, -1 + \/ 3 *I]
>>> solve(x*x+2*x+4)
        ___           ___
[-1 - \/ 3 *I, -1 + \/ 3 *I]
