AttributeError: 'tuple' object has no attribute 'split' with result of input()?
提问by Chris G
(This is Homework)Here is what I have:
（这是家庭作业）这是我所拥有的：
L1 = list(map(int, input().split(",")))
I am running into
我遇到了
File "lab3.py", line 23, in <module>
L1 = list(map(int, input().split(",")))
AttributeError: 'tuple' object has no attribute 'split'
what is causing this error?
是什么导致了这个错误？
I am using 1, 2, 3, 4as input
我1, 2, 3, 4用作输入

You need to use raw_inputinstead of input
你需要使用raw_input而不是input
raw_input().split(",")
In Python 2, the input()function will try to evalwhatever the user enters, the equivalent of eval(raw_input()). When you input a comma separated list of values, it is evaluated as a tuple. Your code then calls spliton that tuple:
在 Python 2 中，该input()函数将尝试eval用户输入的任何内容，相当于eval(raw_input()). 当您输入逗号分隔的值列表时，它会被评估为一个元组。然后您的代码调用split该元组：
>>> input().split(',')
1,2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'tuple' object has no attribute 'split'
If you want to se that it's actually a tuple:
如果你想知道它实际上是一个元组：
>>> v = input()
1,3,9
>>> v[0]
1
>>> v[1]
3
>>> v[2]
9
>>> v
(1, 3, 9)
Finally, rather than listand mapyou'd be better off with a list comprehension
最后，而不是list和map你是同一个列表理解更好
L1 = [int(i) for i in raw_input().split(',')]
