PYTHON INDENTATION

Most of the programming languages provide indentation for better code formatting and don’t enforce to have
it. However, in Python, it is mandatory to obey the indentation rules. Typically, we indent each line by four
spaces (or by the same amount) in a block of code.
Python uses the colon symbol (:) and indentation for showing where blocks of code begin and end. All blocks
start with a colon and then contain the indented lines below it.
In the examples, earlier, you might have seen simple expression statements which didn’t have the indentation.
However, for creating compound statements, the indentation will be utmost necessary.

if a>b: # if block starts here
print(a) # This is part of the if block
else: # else must be at the same level as if
print(b) # This line is part of the else block
