Python

Decorators in pythons:

Simple Example:

• Defining Decorators

  #Decorating result if divider is Zero.
  def decorate_dividation(func):
      def inner_dividation(num1, num2):
          if num2 == 0:
              print('num2 cannot be Zero!!!')
              return
          else:
              return num1 / num2
      return inner_dividation
  

• Using decorator into function

    @decorate_dividation
    def divide(num1, num2):
     print(num1 / num2)
  

Input:

  divide(10, 0)

Output:

  num2 cannot be Zero!!!

Input:

  divide(10,5)

Output:

  2.0
