Why am I getting ModuleNotFoundError when importing matplotlib in Python 3.7 with Anaconda?

If you're a Python developer using Anaconda and Python 3.7, you might have encountered a ModuleNotFoundError when attempting to import matplotlib. This issue can be particularly frustrating, especially if you followed a standard installation procedure. Let's delve into why this error occurs and how you can effectively resolve it to ensure smooth operation of your Python environment.
