Regex to split a line containing commas

Question

How can I break a string with a comma that contains commas in Python? Let say the line:

object = """{"alert", "Sorry, you are not allowed to do that now, try later", "success", "Welcome, user"}"""

How can I get only four elements after splitting?

Answer 1

>>> from ast import literal_eval
>>> obj = '{"alert", "Sorry, you are not allowed to do that now, try later", "success", "Welcome, user"}'
>>> literal_eval(obj[1:-1])
('alert', 'Sorry, you are not allowed to do that now, try later', 'success', 'Welcome, user')

In Python3.2 +, you can just use literal_eval(obj).

Answer 2

>>> import re
>>> re.findall(r'\"(.+?)\"', obj)
['alert', 'Sorry, you are not allowed to do that now, try later',
 'success', 'Welcome, user']
