Python Indentation

Indentation refers to the spaces at the beginning of a code line.

Where in other programming languages the indentation in code is for readability only, the indentation in Python is very important.

Python uses indentation to indicate a block of code.

if 5 > 2:
print("Five is greater than two!")

Python will give you an error if you skip the indentation:

Syntax Error:

if 5 > 2:
print("Five is greater than two!")

The number of spaces is up to you as a programmer, but it has to be at least one.

if 5 > 2:
print("Five is greater than two!")
if 5 > 2:
print("Five is greater than two!")

You have to use the same number of spaces in the same block of code, otherwise Python will give you an error:

Syntax Error:

if 5 > 2:
print("Five is greater than two!")
print("Five is greater than two!")
