Make sum of two integers with extra condition

Sum of two given integers.

However, if the sum is between 15 to 20 it will return 20.

def sum(x, y):
    sum = x + y
    if sum in range(15, 20):
        return 20
    else:
        return sum
# test
print(sum(10, 6))    # 20
print(sum(10, 2))    # 12
print(sum(10, 12))   # 22
