Getting all hard-coded paths out of the code, how to handle the config file?

I'm trying to get all my hard coded paths out of one of my projects and into a config.ini file. The only thing left is the config file itself. Since I have to read it in:

>>> config = ConfigParser.RawConfigParser()
>>> configReader = config.read('config.ini')

I don't know how to get this out of the code (or if it's even possible). So is there a way to get the hardcoded config path out of the code?

You can find the path to a module by using __file__:

#config.py
pass

Importing the module lets you access the name of the file it was imported from:

#main.py
import os
import config

print config.__file__
print os.path.basename(config.__file__)
print os.path.dirname(config.__file__)

Running this in a console gives:

>>> import main
C:/Users/peterwood/Desktop\config.py
config.py
C:/Users/peterwood/Desktop

Not possible AFAIK. The program has to know what file to read somehow. There is nothing wrong with having a hard-coded path of the config file in your program.

Take a command line parameter that specifies where your program can find your configuration file.

Take a look at http://docs.python.org/library/optparse.html and it's newer brother http://docs.python.org/dev/library/argparse.html on how to parse command line parameters in Python.
