Functions and Control Structures

Use this video to reinforce the syntax and applications of if/else/elif statements, loops, and functions. Make sure you feel comfortable writing functions and testing values as they are input and returned from functions that you have written. Additionally, understanding program flow as you navigate through if-elif blocks implies that you can predict the outcome of the block before the code executes. This way, you will convince yourself that you understand how if/else/elif statements work. Finally, practice writing loops and predicting what values variables should take during each loop iteration.
