Python Function

Function is a group of instructions for a specific purpose.

By making function you can use the code as many times as you want

Syntax

 # defining function
def function_name(parameter_list):
   statement_1
   statement_2
   
# Calling a function
function_name(parameter_list)

Example

  1. def scanftree(a, b):
  2.     if a>b
  3.         print a
  4.     else 
  5.         print b       # defining function
  6.         
  7. scanftree(5,6)        # Calling a function

Output

6

  1. def scanftree(a, b):
  2.     if a>b:
  3.         print a
  4.     else:
  5.         print b     # defining function
  6.         
  7. scanftree(5,6)      # Calling function
