You're a square! Python Codewars

 

Given an integral number, determine if it's a square number:

In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself.

The tests will always use some integral number, so don't worry about that in dynamic typed languages.

Examples

-1  =>  false
 0  =>  true
 3  =>  false
 4  =>  true
25  =>  true
26  =>  false

def is_square(n):
    if n < 0:
        return False
    if n >= 0:
        if (n ** 0.5) % 1 == 0:
            return True
        else:
            return False

def is_square(n):    
    return n >= 0 and (n**0.5) % 1 == 0

print(is_square(9))
