Technical requirements
The code in the accompanying repository written for this chapter (https://github.com/PacktPublishing/Hands-On-Software-Engineering-with-Python-Second-Edition/tree/main/CH07-code) was written in and tested with Python 3.11, though some examples are written as examples using syntax and structure going as far back as Python 3.0, for the purpose of showing changes across versions of the language. Even in those cases, they will run under Python 3.11, and probably later versions — Python has a good history of maintaining backward compatibility for several years at a time. The code presented in the text of the book may or may not be executable; much of it is for the purpose of illustrating various points discussed in the text.
Installation packages and instructions for Python 3.11 can be found at https://www.python.org/downloads/, under the Looking for a specific release? heading for Windows and macOS systems. Linux systems typically have access to it through...
