(This is Homework) Here is what I have:
L1 = list(map(int, input().split(","))) I am running into
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?
I am using 1, 2, 3, 4 as input

You need to use raw_input instead of input
raw_input().split(",") In Python 2, the input() function will try to eval whatever 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 split on that tuple:
>>> 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:
>>> v = input() 1,3,9 >>> v[0] 1 >>> v[1] 3 >>> v[2] 9 >>> v (1, 3, 9) Finally, rather than list and map you'd be better off with a list comprehension
L1 = [int(i) for i in raw_input().split(',')]
