Pass Statement :
                  The pass statement in Python is used as a do-nothing placeholder. It allows you to create an empty code block without causing an error.

Why Pass is Needed ?
                   Without pass , this code will cause an error. Python expects a statement inside the block.

Python 
if True: #output IndentationError: expected an indented block
Example :
               
Python 
age = 18 if age >= 18: pass # logic will be added later print("Program continues") #output 
Program continues
