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?

Use split() to split at the commas, use int() to convert to integer:
user_lst = map(int, user.split(","))

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(',')]

[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.

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

Not so good if the user is allowed to enter a single number.

Sure, but that's easy enough to catch.

And things that are not numbers are easy enough to catch.
>>> result = ['12,33,223']
>>> int(result[0].replace(",", ""))
1233233
>>> [int(i) for i in result[0].split(',')]
[12, 33, 233]

You could use the join method and convert that to an integer:
int(''.join(userLst))
1233223

This doesn't really answer the question, or address the actual problem.

@Eevee - How does this not convert a string list into an int?
Ignacio Vazquez-Abrams
It's a single string in a list, not a list of strings.
'" in the list['12,33,223'], you get[12,33,223]-- at least this is how I read it...
