Overview of this book

This is not your average Python programming book, because the world doesn’t need another one of those. Instead, it’s an illustrated, fun, and hands-on guide that treats learning Python like the adventure it should be. It’s designed especially for beginners who want to understand how code works without getting overwhelmed. You’ll be guided by a cheeky, know-it-all cat who’s surprisingly good at teaching Python from scratch. Don’t worry about going through it alone; a slightly moody dachshund dog is your study buddy, learning right alongside you. Each chapter introduces a core programming concept, explains it with a playful twist, and reinforces it through human-friendly examples, analogies, and exercises. Whether you’re a software professional or someone who’s never written a single line of code, this book will help you build real Python coding skills… and even enjoy the process (shocking, right?). Forget dry tutorials and walls of text. Python Illustrated speaks to visual learners, creative thinkers, cat lovers, dog lovers, and anyone who prefers their learning with a dash of humor. From writing your first function to understanding object-oriented programming, you’ll build a solid foundation in Python (without the usual headaches).

Appendix A: Exercise Files

Reading files

Alright, onto the exciting part! Let’s see how we can actually do something with these opened files. Once we have a file open in reading mode, we need to decide how we want to read the contents. Python offers a few different ways of reading that we can choose from.

read() versus readline() versus readlines()

  • read() slurps up the entire file’s content as a single string. If the file is large, that might be a lot of data to swallow at once. If it’s too large (larger than the RAM that the Python program gets to use), the execution will become slow or crash.
  • readline() reads a single line each time it’s called. If you call it in a loop, you can process the file line by line without loading everything into memory at once. This is safer to use as it won’t crash because of the file being too big to swallow at once.
  • readlines() gives us a way of reading all lines at once. We’ll get back a list containing all...
