How to convert a string list into an integer in python [duplicate]

In my python Script I have:

user = nuke.getInput("Frames Turned On")
userLst = [user]
print userLst

Result:

['12,33,223']

I was wondering How I would remove the ' in the list, or somehow convert it into int?

Solution 1:

Use split() to split at the commas, use int() to convert to integer:

user_lst = map(int, user.split(","))

Solution 2:

There's no ' to remove in the list. When you print a list, since it has no direct string representation, Python shows you its repr—a string that shows its structure. You have a list with one item, the string 12,33,223; that's what [user] does.

You probably want to split the string by commas, like so:

user_list = user_input.split(',')

If you want those to be ints, you can use a list comprehension:

user_list = [int(number) for number in user_input.split(',')]

Solution 3:

[int(s) for s in user.split(",")]

I have no idea why you've defined the separate userLst variable, which is a one-element list.

Solution 4:

>>> ast.literal_eval('12,33,223')
(12, 33, 223)
