Learn how to import a Python function from a different file than the one where your main application is coded.

This is a standard practice that allows defining common functions in a single file or module that can then be used by multiple Python programs using the import statement.

In this CodeFatherTech Python tutorial, we will also see the difference between "import {module}" and "from {module} import {function}".

And finally, we will use the Python sys module to add the absolute path where our functions file is located to the Python path.
