Difficulty: introductory

Starter code:

def is_even(n):
	

Solutions:
def is_even(n):
    return not n & 1

def is_even(n):
    return n // 2 * 2 == n

def is_even(n): return n & 1 == 0 


def is_even(n):
    return n/2 == int(n/2)

def is_even(n):
    return str(n)[-1] in '02468'

is_even=lambda n: n|1!=n

def is_even(n):
    return str(bin(n)[2:])[-1] == '0'

def is_even(n):
    return n & 1 ^ 1

def is_even(n): return bin(n)[-1] == "0"

def is_even(n):
    twos = []
    for i in range(0,1000000,2):
       twos.append(i)
    if n in twos:
        return True
    else:
        return False
