How can I loop through all the .py files in my current directory & import a variable from each one?

April 29, 2022

I am in a file called end.py.

In my current directory I have x number of .py files.

Each of these .py files returns a variable called total.

Is it possible, in end.py, to loop through all .py files in the current directory (apart from itself – end.py) and import each file’s total variable & ultimately store the value of each total variable in a list to be used later on in end.py?

>Solution :

You can list the Python files in the current directory:

import pathlib

source_files = pathlib.Path('.').glob('*.py')

Using importlib, you can import these in a loop:

import importlib.util
import pathlib

for source_file in pathlib.Path('.').glob('*.py'):
    name = source_file.stem
    spec = importlib.util.spec_from_file_location(name, source_file)
    mod = importlib.util.module_from_spec(spec)
    spec.loader.exec_module(mod)

In the for loop, you can access the total as mod.total.

To skip a single file, like end.py, you can add:

import importlib.util
import pathlib

for source_file in pathlib.Path('.').glob('*.py'):
    name = source_file.stem
    if name == 'end':
        continue
    spec = importlib.util.spec_from_file_location(name, source_file)
    mod = importlib.util.module_from_spec(spec)
    spec.loader.exec_module(mod)

Note that this will import every module in the current directory. Does that include the current module? You will probably want to skip that one too.
