I have the following string - "['1', '2']" that I need to convert into a

integers. Eg "['1', '7', '4',......,'n']" (values are not sequential)
What would be the best way to do this? I don't want to use eval, as the
string is coming from an untrusted source.
I'd probably use a regex, although others might think it's overkill. :-)
>>> import re
>>> s = "['1', '2']"
>>> [int(n) for n in re.findall(r'-?\d+', s)]
[1, 2]
An alternative is:
>>> s = "['1', '2']"
>>> [int(n.strip("'[] ")) for n in s.split(",")]
[1, 2]
