However, in Python, proper indentation is mandatory as it is used to indicate the beginning and end of code blocks. Incorrect indentation can lead to syntax errors and code malfunctioning.

How to Indent in Python

In Python, an indented block is a set of statements that are intended to be executed together. The standard convention in Python is to use four spaces for each indentation level. It is crucial to be consistent with indentation throughout the code to avoid errors. Python does not allow mixing tabs and spaces for indentation; you must choose one and stick to it.

Examples of Indentation in Python

Let’s consider a simple Python function to demonstrate the importance of proper indentation:

def greet(name):
    if name:
        print("Hello, " + name + "!")
    else:
        print("Hello, there!")

greet("Alice")

In this example, the print statements inside the if and else blocks are indented to show that they are part of the respective conditions.

Resolving Indentation Errors in Python
