Indentation

 Indent is cursor position used to represent group of statements. At the interactive prompt, we have to type a tab or space(s) for each indented line.

All decent text editors have an auto-indent facility. Each line within a basic block will have same amount of indent

Ex:

 Sum.py

def add ( ):                         a = int (input (“Enter first value”))                         b = int (input (“Enter second value”))                         print (“Sum of two numbers”, a+b)                add ( )
