尝试拆开非序列的夹板（拆包非序列）

谁能告诉我这段代码有什么问题：

def greater(a,b):
    if a > b:
        return a
    return b

num1, num2 = int(input("enter two number : ").split(","))
print(f"bigger is :  {greater(num1,num2)}")


TypeError: int() argument must be a string, a bytes-like object or a number, not 'list'

你有

  • input("enter two number : ") that values let's say 1,2

  • input("...").split(",") is now ['1', '2'] so a list of 2 string

  • int(['1', '2']) << you can't do that

You need to map each value to int

num1, num2 = map(int,input("enter two number : ").split(","))

还是做

values = input("enter two number : ").split(",")
num1, num2 = int(values[0], int(values[1])
