Answer 1

This one also works.

• Pros: it supports from ... import ... instead of module.my_function, and it does not require to write the module as a string.
• Cons: it needs the module to be imported.

# Import of my_function and module
import my_utils
from my_utils import my_function

# Test:
my_function()

# For reloading:
from importlib import reload
reload(my_utils)
from my_utils import my_function

# Test again:
my_function()
