python run all py files from main py file

[mg24]

Hi Gribouillis,

Superb ! your code worked ,
you are genius ! thanks for your help, you have saved my time.

Is there any other style way. I heard about multiprocessing\Multitreading\subprocess .run.

from pathlib import Path
import sys
this_dir = Path(__file__).parent
 
for args in [
    "add.py 10 20 30",
    "sub.py  40 20",
    "mul.py  2 2 2 2",
    "div.py   100 50"]:
    args = args.split()
    filename = this_dir/args[0]
    args[0] = str(filename)
    sys.argv[:] = args
    namespace = {'__name__': '__main__'}
    exec(filename.read_text(), namespace)
