Putting integers in lists in python

I am making an nth term calculator and I want the user to enter any sequence they like.

Say if they put: 12, 16, 20, 24, it will be stored in a list like [12, 16, 20, 24]

How can I do this?

If you are getting the input as a string, you can just do the following: map(lambda x: int(x), "12, 16, 20, 24".split(","))

More generally, you would want to do:

nums = raw_input()
map(int, nums.split(","))

The simplest way is to use the split method:

map(int, raw_input().split(","))

Make sure to split only by "," not by ", ", because the latter will raise a ValueError for an input like "12,14,17":

Here's a list comprehension method:

in_str  = "1, 2, 3, 4"
listed = [int(x) for x in in_str.split(',')]
