Say I have a string: 'src.utils.random_num'

How can I import random_num and actually execute it. What I have thus far:

from importlib import import_module


def parse_module(module_path):
    package = '.'.join(module_path.split('.')[:-1])
    module = module_path.split('.')[-1]
    return package, module

req_import = parse_module('src.utils.random_num')
# import the package, works fine
module = import_module(req_import[0])

# how can I access and execute `random_num` via `req_import[1]`?
module.random_num()

How can I evaluate that random_num is a function and execute it dynamically?

Use the spec_from_file_location from importlib.util. You create the spec and then module_from_spec(spec) and load it. – Devon Horizon Feb 07 '20 at 06:30
@DevonHorizon awesome, I’ll take a look! Really appreciate it – sgerbhctim Feb 07 '20 at 06:31
One thing to note, I did make the assumption that you needed to load a module from a file location. with a namespace you could use other better options. – Devon Horizon Feb 07 '20 at 06:41
@DevonHorizon AFK now but if you’d post some examples in the answers that would be amazing.. really appreciate you helping me out. Thank you! – sgerbhctim Feb 07 '20 at 06:42
