I need to get Path for PyQt library in python program. Program is run as a script from another application, therefore my 

sys.executable = 'D:/program files/visum/exe/visum115.exe

and I need my actual python path (and path for PyQt library module)

Path = C:\Python25\Lib\site-packages\PyQt4\plugins

im trying with 

os.environ['PYTHONPATH']

but I'm not sure if it can be robust.

Regards!

PS. I need it to be able to plug plugins:

qApp.addLibaryPath('C:\Python25\Lib\site-packages\PyQt4\plugins')

you can try to load the module and after check for it's __file__ attribute to get the path of the .pyc file.

for example like this:

import MODULE, os
path = os.path.dirname(MODULE.__file__)

  • this will not work with namespace packages, u will get: `AttributeError: module 'MODULE' has no attribute '__file__'` – lnshi Apr 13 '21 at 09:22

What you're looking for is sys.path:

>>> import sys
>>> sys.path
 ['',
 '/usr/lib/python2.7/site-packages/virtualenvwrapper.github-0.1-py2.7.egg',
 '/usr/lib/python2.7/site-packages/pycharm-debug.egg',
 '/usr/lib/python2.7/site-packages/Fom-0.9.2-py2.7.egg',
 '/usr/lib/python2.7/site-packages/blinker-1.1-py2.7.egg',
 '/usr/lib/python2.7/site-packages/httplib2-0.6.0-py2.7.egg',
 '/usr/lib/python27.zip',
 '/usr/lib/python2.7',

A very simple solution:

import PyQt

PyQt.__file__
