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

Python Challenges - 1: Exercise-2 with Solution

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

Explanation:

Sample Solution:

Python Code:

def is_Power_of_three(n):
    while (n % 3 == 0):
         n /= 3;         
    return n == 1;

print(is_Power_of_three(9))
print(is_Power_of_three(81))
print(is_Power_of_three(21))

Sample Output:

True                                                                                                          
True                                                                                                          
False
