Write a Python function to check whether a number is "Perfect" or not.According to Wikipedia : In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also k...
Suppose we have a number n. We have to check whether n is Euclid number or not. As we know Euclid numbers are integer which can be represented as n= Pn+1 where is product of first n prime numbers. So, if the input is like n = 211, then the output will be True n can be ...
print(is_even(31)) Output: True False I have executed the above example code and added the screenshot below. In this code, theis_evenfunction takes a number as input and uses the modulo operator to check if it is divisible by 2. If the remainder is 0, the function returnsTrueindicatin...
type of number class 'str' As you can see, The output shows the type of a variable as a string (str). Solution: In such a situation, We need toconvert user input explicitly to integer and floatto check if it’s a number. If the input string is a number, It will get converted ...
