How to import a Python file with a variable name?

Question

I need to import a python file lets name it 123xzy.py My problem is that this file name starts with numbers, and changes with every use.

I tried to use the following approach:

vt=str(sys.argv[2])
import vt

but its not working. If you know a way to import a python file with a variable name please let me know.

Thank you :)

"its not working" is not very descriptive. Please provide a [mcve] and give the full traceback. — John Coleman, Apr 22 '21 at 11:02

Use the standard library package importlib:

import importlib
import sys
vt = importlib.import_module(sys.argv[2])

Also your module name should not end with .py – mousetail Apr 22 '21 at 11:03
ok the problem is solved, thank you I only had to remove the .py part from argv[2] befor the import line vt=re.sub('.py$','',vt) – Sara Awwad Apr 22 '21 at 11:08
