Python modules in Jupyter and Google Colab (03 lecture part c video 1)

This is a good video for anyone new to using Python and Jupyter and interested in creating/utilizing user-defined modules especially in a Google Colab environment. We discuss how to mount your Google Drive within a Jupyter notebook in Colab, how to get an online text editor setup as an integrated app within your Google Drive, and how to reload an edited module so that the changes are reflected within the notebook without having to restart the runtime. We use a "differences" module as an example that approximates the derivatives of a function and discuss, at a high-level, the concept of a derivative and its applications.
