Question

I have an python application that need to know in which directory it founded when it run,

how can i know the running application path on windows for example when i change the directory path is changed to the new directory .

is there a way to know where is the python application run withour saving it on the beginning by os.path.abspath(os.path.dirname(file))

for example the to know where the application runs after os.chdir("c:/")

     import os 
     print os.path.abspath(os.path.dirname(__file__))
     os.chdir("c:/")
     print os.path.abspath(os.path.dirname(__file__))

it is contained in the __file__ variable.

But if you want to know the current working directory then you should use os.getcw.

>>> os.getcwd()
'C:\\Program Files\\Python31'
>>> os.chdir(r'C:\\')
>>> os.getcwd()
'C:\\'

import os
print os.path.abspath(os.path.dirname(__file__))
