Python-3.x：使用以下代码时出现错误，因为“对象没有属性'split''”

Question

n = int(input())
arr = [int(x) for x in input.split()]

this is the code i used. I want to get list of input from the user but i am getting error as

    arr = [int(x) for x in input.split()]
    AttributeError: 'builtin_function_or_method' object has no attribute 'split'

Answer 1

You are calling split on the builtin function input . While what you should be doing is calling it on the n variable. So it should look like this

n = int(input()) 
arr = [int(x) for x in n.split()] # Still wrong

But still let me quote that int however has no split attribute. So make sure it is a String type.

So your try not to convert your input into int until you process the value.

Answer 2

You're trying to split the input function itself, and not its results. You need to split the string it returns, like this input().split() . Mind you that this will not do anything because split has no parameters. It'll simply return a list with the user's input as the sole parameter. If you want to divide the input string into its chars, you can simply use list(input()) .

Answer 3

I believe this is what you are going for, turn the input to a list and ints for items in the list

  l = [int(i) for i in list(input('Enter number: '))]

 Enter number: 101 [1, 0, 1] 

Answer 4

As Vineeth said, you are trying to call split on input. Also, you can't split an integer since split is a method that can only be used on strings, so you shouldn't cast n as an integer.

n = str(input())
arr = [int(x) for x in n.split()]
