Welcome to Day 65 of The Complete Python Bootcamp.
In this session, you will explore the importance of indentation in Python, a fundamental concept that defines how your code is structured and executed.
Unlike many other programming languages, Python uses indentation to group statements into blocks. This means indentation is not just about style, it directly affects how your program runs. Proper indentation tells Python which lines of code belong together, whether inside an if statement, loop or function.
Today, you will learn why indentation matters, how it controls program flow and how to avoid common errors caused by incorrect spacing.
By the end of this lesson, you will understand how to structure your code clearly and write clean, error free Python programs.
