python - 用于拆分包含逗号的字符串的正则表达式？

Question

如何在 Python 中用逗号拆分包含逗号本身的字符串？假设字符串是:

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

如何确保拆分后只得到四个元素？

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')

On Python3.2+您可以简单地使用 literal_eval(obj)。
