Oh my god, I finished the basics of python within one day (continues 10 
hours)!!!
What's amazing language :-*

Actually I found some principles like extended C++ libraries, for 
example I'm using Qt classes for creating objects just like dictionary 
in python, where python provides them by default wow =-O .

PyDev is amazing specially I'm familiar with eclipse (I was using it 
before releasing Qt Creator) but as I can see it's suitable for web 
applications (specially with Aptana) more than desktop application 
because web application don't need visual editor but in case if I want 
to develope dektop applications (of course in the future) what's most 
suitable IDE for that?

Until now I tested the following:

   1. PyDev <http://www.pydev.org/index.html> (95/100): amazing and gave
      a good impression for first look but it's not supporting visual
      editor for desktop applications.
   2. eric <http://eric-ide.python-projects.org/index.html>(80/100): the
      most active IDE for desktop applications in python but it has many
      negatives like autocompleting is so stupid managing the projects
      syncing changes between UI files and the code bad interface.
   3. boa-constructor
      <http://prdownloads.sourceforge.net/boa-constructor/> (70/100):
      generally it has only two negatives it uses wxPython and it's not
      active since 2007 although I prefer it more than eric but I really
      hate wx
   4. SPE
      <https://sourceforge.net/project/showfiles.php?group_id=145384>(50/100):
      most likely to eric by it has arranged interface, uses wxPython
      and it's not active since 2006 (dead project)

I found many IDEs for desktop application but most of them very simple 
or/and dead (PythonCard... etc)

Do u've more details?

Could you guide me to quick guide for learning CGI?
