Python Day 17: More Exceptions

Write a Calculator class with a single method: int power(int,int). The power method takes two integers, n and p, as parameters and returns the integer result of n^p. If either n or p is negative, then the method must throw an exception with the message: n and p should be non-negative



  1. #Write your code here

  2. class e(Exception):

  3.     "n and p should be non-negative"

  6. class Calculator():

  7.     def power(self, n, p):

  8.         try:

  9.             if n | p < 0:

  10.                 raise e

  11. 

  12.             else:

  13.                 return (n ** p)

  14.         except e:

  15.             return ("n and p should be non-negative")

  16. 

  17. myCalculator=Calculator()

  18. T=int(input())

  19. for i in range(T):

  20.     n,p = map(int, input().split())

  21.     try:

  22.         ans=myCalculator.power(n,p)

  23.         print(ans)

  24.     except Exception as e:

  25.         print(e)
