Python: Import from variable after finding all files in dir

Question

I'm trying to make a python program for a given software than will scan&run another certain python function at choice (or .py file altogether). However I can't import a function name set in a variable.

import glob

functions_list = glob.glob('*.py')
#all my python files are found
#pick any specific file to import
import a[3]

This fails with SyntaxError: invalid syntax.

Is there any way to do this? My idea is to have a TkInter selection list where I click to run the .py I selected.

Why not run the script inside a subprocess using a shell command?

subprocess.call(['python', a[3])

You should have a look at python's imp module. It enables you to dynamically load modules at runtime and then execute their functions.

This has been deprecated since 3.4, one should use `importlib` instead – juanpa.arrivillaga Sep 28 '18 at 20:27
fp, pathname, desc = imp.find_module(a[0].strip('.py')) /n imp.load_module(a[0].strip('.py'),fp,pathname,desc) /n This worked – João Mamede Sep 28 '18 at 20:55
