Description :
Write a Python program to check if a number is a power of a given base
Source Code:
import math
def isPower (n, base):
if base == 1 and n != 1:
return False
if base == 1 and n == 1:
return True
if base == 0 and n != 1:
return False
power = int (math.log(n, base) + 0.5)
return base ** power == n
print(isPower(127,2))
print(isPower(128,2))
print(isPower(27,2))
print(isPower (27,3))
print(isPower (28,3))
print(isPower (2**10,2))
print(isPower (2**12,2))
print(isPower(2,2))
print(isPower(5,5))
print(isPower(10,1))
Sample Output:
False True False True False True True True True False
