[Tutor] python function to know the path of the program in execution *

Fri Feb 5 14:13:18 CET 2010

If you want to know the file you're script is running from then print 
sys.argv[0]

this is the script I ran from a file named lowerdir.py:
import sys
print 
"This is sys.path:"
print
print sys.path
print
print "This 
is sys.path[0], the current working directory:"
print
print 
sys.path[0]
print
print "This is sys.path[1], the first in the 
PYTHONOPATH string after the current directory your script is running 
in:"
print
print sys.path[1]
print
print "This is 
sys.path[-1] the last in the PYTHONPATH list:"
print
print 
sys.path[-1]
print
print "This is sys.argv[0] your current running
 scripts full path:"
print
print sys.argv[0]

This is my
 output:

IDLE 2.6.4      
>>> 
================================ RESTART
 ================================
>>> 
This is sys.path:

['C:\\Python26\\testingscripts\\lowerdir',
 'C:\\Python26\\Lib\\idlelib', 'C:\\Windows\\system32\\python26.zip', 
'C:\\Python26\\DLLs', 'C:\\Python26\\lib', 
'C:\\Python26\\lib\\plat-win', 'C:\\Python26\\lib\\lib-tk', 
'C:\\Python26', 'C:\\Python26\\lib\\site-packages', 
'C:\\Python26\\lib\\site-packages\\win32', 
'C:\\Python26\\lib\\site-packages\\win32\\lib', 
'C:\\Python26\\lib\\site-packages\\Pythonwin']

This is 
sys.path[0], the current working directory:

C:\Python26\testingscripts\lowerdir

This
 is sys.path[1], the first in the PYTHONOPATH string after the current 
directory your script is running in:

C:\Python26\Lib\idlelib

This
 is sys.path[-1] the last in the PYTHONPATH list:

C:\Python26\lib\site-packages\Pythonwin

This
 is sys.argv[0] your current running scripts full
 path:

C:\Python26\testingscripts\lowerdir\lowerdir.py
>>>

As long as you have sys imported at somepoint, then all you
 have to do is print sys.argv[0], and that should be the exact name and 
location of the current running script,

I remember using the __file__ attribute in Django once. I don't know if 
that's what you are looking for. You might want to take a loook at
