Python Challenges: Check if a given positive integer is a power of two

Python Challenges - 1: Exercise-1 with Solution

Write a Python program to check if a given positive integer is a power of two.

Explanation:

Sample Solution:

Python Code:

def is_Power_of_two(n):
        return n > 0 and (n & (n - 1)) == 0
print(is_Power_of_two(4))
print(is_Power_of_two(36))
print(is_Power_of_two(16))

Sample Output:

True
