What is the Python equivalent of Perl's FindBin? [duplicate]

Question

In Perl, the FindBin module is used to locate the directory of the original script. What's the canonical way to get this directory in Python?

Some of the options I've seen:

• os.path.dirname(os.path.realpath(sys.argv[0]))
• os.path.abspath(os.path.dirname(sys.argv[0]))
• os.path.abspath(os.path.dirname(__file__))

Answer 1

To update on the previous answers, with Python 3.4+, you can now do:

import pathlib
bindir = pathlib.Path(__file__).resolve().parent

Which will give you the same, except you'll get a Path object that is way more nice to work with.

Answer 2

You can try this:

import os
bindir = os.path.abspath(os.path.dirname(__file__))

That will give you the absolute path of the current file's directory.

Answer 3

I don't use Python very often so I do not know if there is package like FindBin but

import os
import sys
bindir = os.path.abspath(os.path.dirname(sys.argv[0]))

should work.
