Program 5: Write a function perfectNumber(number) that takes an integer argument number as an input and
checks whether the number is a perfect square or not. In number theory, a perfect number is a positive integer that
is equal to the sum of its positive divisors, excluding the number itself. Invoke the function to print an appropriate
message for the user-entered number.

Ans. def perfectNumber(number):
'''

Objective : To check whether a number is perfect number
Input Parameter : number - numeric value
