Why is indentation considered important in Python scripts?

Indentation in Python is critical because it serves to indicate the structure of the code, particularly in defining scope and managing flow control. Unlike some other programming languages that use braces or keywords to determine block levels of code (such as if statements, loops, and function definitions), Python relies entirely on indentation levels. This means that the way code is indented not only makes it more readable but also dictates how the program is interpreted and executed.

For example, in conditional statements or loops, the lines of code that belong to those structures must be consistently indented. If code that is supposed to be part of a loop or a function isn't indented correctly, Python will throw an indentation error, or worse, lead to logical errors where the wrong lines of code are executed.

Therefore, indentation is not just a matter of style but a fundamental aspect of Python code that impacts its behavior and execution. Maintaining consistent indentation is essential for ensuring that the code operates as intended. This clear structure helps both the programmer and anyone else reading the code to understand the relationships and hierarchies within the script.
