python - 这个简单的代码给了我硬语法错误，除数代码

Question

def main():
    user_number = float(input("Enter a number: "))
    num = user_number//2
    round(num,0)
    int(num)
    print(num)
    divisor = 1
    for divisor in range(divisor,num):
        if num%divisor == 0:
                print(divisor)

while True:
    main()

我得到的语法错误：TypeError: 'float' object cannot be Explained as an integer

Answer 1

结果num = user_number // 2是一个浮点数。

该调用round(num, 0)什么也不做，因为您没有将结果存储在num变量中。无论如何，结果是float. 你应该改写num = int(num)。
