This is a presentation of Chapter 2 of the "Introduction to Python & Programming" book that accompanies the coding course in the Bachelor program at WHU - Otto Beisheim School of Management in Germany in the spring semester 2020.

In this video, I talk about:
How Python comes with many functions already built in
What the built-in constructors are
How to make code re-usable by writing new functions
How calling a function creates a new scope in the memory
What the scoping rules (i.e., local scope disappearing, global scope, and shadowing)
What different ways exist to define the parameters a function takes
How to import further functions from the standard library
How to install third-party libraries and use functions provided by them
How code can be stored in .py files and imported in a Jupyter notebook
