How to Open Files in the Same Directory as Your Python Script?

File Opening in Same Directory as Running Script

When working with Python scripts, reliably opening files in the same directory as the running script is crucial. However, using commands like open("Some file.txt", "r") may encounter issues if the script is executed via double-clicking in Windows.

Problematic and Reliable Techniques

Techniques that may fail include:

• os.getcwd() and os.path.abspath('') return the current working directory, not the script directory.
• os.path.dirname(sys.argv[0]) and os.path.dirname(__file__) may return a relative or blank path, and __file__ is unavailable in certain environments.

A reliable method is:

__location__ = os.path.realpath(
    os.path.join(os.getcwd(), os.path.dirname(__file__)))

This combines the current working directory with the path derived from __file__. If __file__ is absolute, the prefix is removed. Realpath handling ensures that any symbolic links are resolved.

Opening Files

To open a file in the same directory, use the following syntax:

f = open(os.path.join(__location__, 'bundled-resource.jpg'))

This ensures that the file is located in the same directory as the running script. The technique works reliably in both Windows and Linux environments, handling double-clicking and resource bundling scenarios effectively.
