How to convert a string list into an integer in python
This question already has an answer here:
使用split()在逗号分割，使用int()将其转换为整数：
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 int s, you can use a list comprehension:
user_list = [int(number) for number in user_input.split(',')]
[int(s) for s in user.split(",")]
我不知道为什么你定义了单独的userLst变量，它是一个元素列表。
