And if you’re going to write some code, you’ll need a real problem. As luck would have it, we have one of those. In this chapter, you’ll start your Python application development journey by making a splash with our friendly, neighborhood, Swim Coach. You’ll begin with Python strings, learning how to manipulate them to your heart’s desire, all the while working your way towards producing a Python-based solution to the Coach’s problem. You’ll also see more of Python’s built-in list data structure, learn how variables work, and discover how to read Python’s error messages without going off the deep end, all while solving a real problem with real Python code. Let’s dive in (head first)…

During a training session, he records each swimmer’s training times on his trusty clipboard then, later at home, manually types each swimmer’s times into his favorite spreadsheet program in order to perform a simple performance analysis.
