Python How to import and use a module from another Python program online?

[SMSteven]

Hi All

I'm learning Python.

I have created a typical sample module online (specifically on repl.it):

[CODE lang="python" title="module example"]# Python Module example

def add(a, b):
"""
This program adds two
numbers and returns the result.
"""

return a + b
[/CODE]

Here, the module file name is example.py, the module is named example and it contains a sample function add(a, b) which returns the sum of the parameters.

I have no problem accessing this sample function from file main.py in the same program. It works perfectly, once the import is done:

[CODE title="import example module - same program"]
import example
print("example.add(2, 12) = ",
example.add(2, 12))
[/CODE]

However, when I try to access module example from another program, it is not possible, since the Python interpreter can't locate example module (screenshot attached).

How can I do this (assuming the Python program accessing example module will be distinct from the program containing function add()?

I am asking this particularly in the context of online websites (such as repl.it) where I can create such programs entirely online.
