In this chapter, we鈥檒l further our understanding of Booleans and Boolean expressions, learn about branching and flow control, and learn some convenient string methods.

Learning objectives

  • You will learn more about Booleans, how to construct a truth table, and how to combine Booleans using the connectives and and or.
  • You will learn how to write if, if/else, if/elif, and if/elif/else statements in Python, which allow program execution to follow different branches based on certain conditions.
  • You will learn how to represent decisions using and decision trees.
  • You will learn a little about input validation.
  • You will learn how to use convenient string methods such as .upper(), .lower(), and .capitalize().
