Multi-processing - problem with running multiple *.py files at the same time

[Antonio]

I check the task manager and it's only one core of the CPU that is working; plus the time is 5 times more than running a single file (I have 5 files in the loop as you see). The point is, how do I run the for loop in parallel?

Hi there,

I have multiple *.py files that I need to run concurrently. Each file looks like this:

def my_function(file):

    # my code

Then I have written this to run my files simultaneously:

import multiprocessing

from file1 import my_function

if __name__ == '__main__':
    __spec__ = "ModuleSpec(name='builtins', loader=<class '_frozen_importlib.BuiltinImporter'>)" # This line is because I am using Spyder as my IDE

    files = ["path/to/file1.py","path/to/file2.py","path/to/file3.py","path/to/file4.py","path/to/file5.py"]

    for item in files:
        p = multiprocessing.Process(target=my_function, args=(item,))
        p.start()
        p.join()
        print("Done!")

The issue is that, however, the files are still being run one after another like in a sequence but not in parallel! Do you have any ideas how I may run my files concurrently?
