Python Identify File Path to Module -

the regular os.path.dirname(__file__) doesn't work in special setting i'm in. hope not having influence, it's jython 2.7.

text_dir = os.path.dirname(__file__) nameerror: global name '__file__' not defined

if call os.path.dirname(__file__) inside function works fine.

version 1 (works)

bar.py

import os def bar():   location = os.path.dirname(__file__)   return location

version 2 (doesn't work, see above nameerror)

extension.py

import os some_tool import extensions class extended(extensions):   def foo():     location = os.path.dirname(__file__)

any idea why? related jython? or because inside class? or because inherting something?

current workaround

extension.py

import bar some_tool import extensions class extended(extensions):     def foo():         location = bar.bar()

it worked me:

 $ pwd /tmp  $ cat test.py import os; print(os.path.dirname(os.path.realpath(__file__)))  $ python test.py /tmp

'__file__' works me well.
