How Can I Import A Python 3 Module With A Period In The Filename?

What is the proper way to import a script that contains a period, such as program_1.4.py, ideally using importlib?

(Now that the imp module is deprecated, this this answer no longer applies: How to reference python package when filename contains a period .)

Solution

  • After looking through the CPython quite a lot and coming back to some other solutions (especially Import arbitrary python source file. (Python 3.3+)), I realized that I needed to pass the full path to my module. Here is the cross-platform, call-location-independent solution:

    """

    import os, sys # For running from Notepad++ shortcut, etc
import importlib.machinery

program_1_4 = importlib.machinery.SourceFileLoader('program_1.4', os.path.join(sys.path[0], 'program_1.4.py')).load_module()

print(program_1_4)
program_1_4.main()

    """
