Дайте идея защо първият ми тест гърми :?

N1 = int(input())
N2 = int(input())
operator = str(input())

result = 0

if operator == "+":
    result = N1 + N2
elif operator == "-":
    result = N1 - N2
elif operator == "*":
    result = N1 * N2
elif operator == "/" and N2 != 0:
    result = round((N1 / N2),2)
elif operator == "%" and N2 != 0:
    result = N1 % N2

if  operator == "%" or operator == "/":
    if N2 == 0:
        print(f"Cannot divide {N1} by zero")
    elif operator == "/":
        print(f"{N1} / {N2} = {result}")
    elif operator == "%":
        print(f"{N1} % {N2} = {result}")
elif operator == "+" or operator == "-" or operator == "*":
    if result % 2 == 0:
        print(f"{N1} {operator} {N2} = {result} - even")
    else:
        print(f"{N1} {operator} {N2} = {result} - odd")
