How do I get the location of the entry module in python?

Question

I know I can use __file__ and os.path.* to figure out the path of the current module. What about the entry module?

I'm trying to load an ini file into ConfigParser from a module based on the hostname, but I want it to be relative to the entry assembly, not necessarily the working directory. Is this possible?

If by entry module you mean the program's entrypoint this is usually sys.argv[0]. So you could do something like this:

Example:

import os
import sys


def main():
    basedir = os.path.dirname(sys.argv[0])
    print "base directory: {0:s}".format(basedir)


if __name__ == "__main__":
    main()
