Reloading a Python module that has been imported in another file can be useful during development when you want to apply changes to the module without restarting the entire application. The importlib module in Python provides a function called reload that allows you to reload a previously imported module. In this tutorial, I'll guide you through the process with a simple example.
Let's assume you have two files: main.py and module_to_reload.py. The goal is to import module_to_reload.py into main.py and then reload it dynamically.
Execute main.py in your terminal or preferred Python environment:
Initial Import: main.py initially imports module_to_reload.py and calls the greeting() function.
