Windows Service relative path issue in Python

Question

I have written a small Windows Service compiled to an exe using py2exe, which from I read a file. It works great - however - I can only use an absolute path to access the file, using a relative path won't work. In .net you can do something like:

System.Reflection.Assembly.GetEntryAssembly().Location

To get the path to the .exe file, is there an option similar to this but for Python?

Best Regards,

Answer 1

You have a couple of options. If you already have a module object, you can do <module>.__file__ to get the path:

>>> import time
>>> time.__file__
'/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/time.so'

However, often times you want to know the location of your current module, in which case you can use:

import inspect

path = inspect.currentframe().f_code.co_filename

(Also keep in mind that this can be anything that can be loaded by Python - so it can be a .pyd, .pyc, .so, .dll, etc.)
