Python Indentation

Indentation means adding spaces at the beginning of a line to define code blocks.

In Python, indentation is required. It tells Python which lines belong together.

file: 6_indentation.py

if True:
    print("Hello")
    print("World")

output

Hello
World

Here, both print() statements are inside the if block because they are indented.

If indentation is wrong, Python will give an error.

if True:
print("Hello")

❌ This will cause an IndentationError.

Note

Python uses indentation (spaces) to define structure, instead of {} like some other languages.
