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
Scripts>pip3.4.exe install facepy

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
Installing collected packages: wheel

Successfully installed wheel-0.24.0

C:\Python27\Scripts>pip2.7 install --upgrade pip
Collecting pip from https://pypi.python.org/packages/py2.py3/p/pip/pip-6.0.8-py2
.py3-none-any.whl#md5=41e73fae2c86ba2270ff51c1d86f7e09
  Downloading pip-6.0.8-py2.py3-none-any.whl (1.3MB)
    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
Collecting PyOpenGL
  Downloading PyOpenGL-3.1.0.tar.gz (1.2MB)
    100% |################################| 1.2MB 2.2MB/s ta 0:00:01
Installing collected packages: PyOpenGL
  Running setup.py install for PyOpenGL
Successfully installed PyOpenGL-3.1.0
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

Successfully installed pygame-1.9.2a0

News : PythonAnywhere come with good news.

The author Giles tells us:
Obviously, the most important thing we did was to switch out our javascript console for a new one that supports 256 colours! And slightly more sane copy + paste. And it works on Android, or at least it does on Lollipop. Giles recommends the Hackers keyboard. Still doesn't work on my blackberry though.
As you know :
PythonAnywhere is a Python development and hosting environment that displays in your web browser and runs on our servers. They're already set up with everything you need. It's easy to use, fast, and powerful. There's even a useful free plan.
I worked with PythonAnywhere and is very good. Thank you Giles.

YARA python module - part 001 .

You can also see more python tutorial on free-tutorials.org.
YARA is a multi-platform program running on Windows, Linux and Mac OS X.
More about yara python module can be see it here
YARA used this keywords with rules under files.
all  and  any  ascii  at  condition  contains
entrypoint  false  filesize  fullword  for  global  in
import  include  int8  int16  int32  int8be  int16be
int32be  matches  meta  nocase  not  or  of
private  rule  strings  them  true  uint8  uint16
uint32  uint8be  uint16be  uint32be  wide

The Yara documentation can be found in this link.
The yara python module use version 1.7.7 and this will need to use when make rules.
Instalation with pip :
C:\Python34>cd Scripts
C:\Python34\Scripts>pip install yara
Downloading/unpacking yara
Installing collected packages: yara
  Running setup.py install for yara

    Installing yara-ctypes-script.py script to C:\Python34\Scripts
    Installing yara-ctypes.exe script to C:\Python34\Scripts
Successfully installed yara
Cleaning up...
Let's see this in action.
First you need to make your user under your_user account.
I make one folder named yara to keep the my rules, see:
C:\\Users\\your_user\\Dropbox\\yara\\
and I test this file named doc_data.txt, from here:
C:\\Users\\your_user\\Dropbox\\
The file has this text :
InfoKey: Creator
InfoValue: TeX
InfoKey: Producer
InfoValue: pdfTeX-1.40.3
InfoKey: PTEX.Fullbanner
InfoValue: This is pdfTeX using libpoppler, Version 3.141592-1.40.3-2.2 (Web2C 7.5.6) kpathsea version 3.5.6
InfoKey: ModDate
InfoValue: D:20110210185614-08'00'
InfoKey: CreationDate
InfoValue: D:20110210185614-08'00'
PdfID0: 5691a9b61e98f4c329d4f9f6deb5363c
PdfID1: 5691a9b61e98f4c329d4f9f6deb5363c
NumberOfPages: 24
and the rule file detectstring has this rule:
rule detectstring
{
    strings:
        $my_text_string = "5691a9b61e98f4c329d4f9f6deb5363c"

    condition:
        $my_text_string 
}
You can use python shell with this source code:
import yara
from yara import *
dir(yara)
['CALLBACK_ABORT', 'CALLBACK_CONTINUE', 'INCLUDE_PATH', 'Rules', 'YARA_RULES_ROO
T', 'YaraSyntaxError', '__builtins__', '__cached__', '__doc__', '__file__', '__l
oader__', '__name__', '__package__', '__path__', '__spec__', '__version__', 'com
pile', 'libyara_wrapper', 'load_rules', 'preprocessor', 'rules', 'version']
print(yara.version.__version__)
1.7.7
rules=yara.compile("C:\\Users\\your_user\\Dropbox\\yara\\detectstring")
matches=rules.match("C:\\Users\\your_user\\Dropbox\\doc_data.txt")
print(matches)
{'main': [{'tags': [], 'matches': True, 'rule': 'detectstring', 'meta': {}, 'str
ings': [{'flags': 19, 'identifier': '$my_text_string', 'data': '5691a9b61e98f4c3
29d4f9f6deb5363c', 'offset': 326}, {'flags': 19, 'identifier': '$my_text_string'
, 'data': '5691a9b61e98f4c329d4f9f6deb5363c', 'offset': 367}]}]}
The above rule is telling YARA that the file containing the string must be reported.
The print will show the rule compiled and the result.

Windows all modules for python 3.4

Most users have a lot of problems with modules.
It's difficult to developing some script from python 2.7 to python 3.x ,common error is print.
First step in this case is to install modules.
You can found all windows modules here.
All this is packed into executable and will find your folder with your python 3.x
For example the executable module named : pygame‑1.9.2a0.win‑amd64‑py3.4.exe shows us through the contents of the file name:
  • will install pygame module version 1.9.2a0 windows version
  • on amd64 operating systems
  • into python version 3.4

very simple to use it.
