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

Answer 1

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

Answer 2

[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.

Answer 3

>>> result = ['12,33,223']
>>> int(result[0].replace(",", ""))
1233233
>>> [int(i) for i in result[0].split(',')]
[12, 33, 233]

Answer 4

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

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

Answer 5

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(',')]

Answer 6

You could use the join method and convert that to an integer:

int(''.join(userLst))    

1233223
