Python 实现简单整数计算器

def calculator(): num1 = int(input()) num2 = int(input()) operator = input()

if operator == '+':
    print(num1 + num2)
elif operator == '-':
    print(num1 - num2)
elif operator == '*':
    print(num1 * num2)
elif operator == '/':
    if num2 == 0:
        print('Divided by zero!')
    else:
        print(num1 / num2)
else:
    print('Invalid operator!')
