Dynamic module import in Python

I need a functionality that allows users to import multiple modules from the command line. So first let’s set up the code that allows users to pass as many arguments as they want into a list:

import argparse

parser = argparse.ArgumentParser()
parser.add_argument("cmd", action="store", nargs='*')
args = parser.parse_args()
args_list = args.cmd

I know you can import as many modules as you want using this syntax:

import sys, os, math

So now I just need to find a way to unstring each element from that list(args_list) of strings with module names so I can do the following:

for el in args_list:
    import unstring(el)

Answer 1

Use this:

for el in args_list:
    globals()[el] = __import__(el, globals(), locals())
