You can do:
def str2tuple(s):
"""Convert tuple-like strings to real tuples.
eg '(1,2,3,4)' -> (1, 2, 3, 4)
"""
if s[0] + s[-1] != "()":
raise ValueErro

Just be sure you know where your strings come from. You wouldn't want
someone to pass you
"""__import__('os').system('rm -rf /')"""
and then send that to eval. =)

py> tuple(int(s) for s in '(1,2,3,4)'[1:-1].split(','))
(1, 2, 3, 4)
Or if you're feeling daring:
py> eval('(1,2,3,4)', dict(__builtins__=None))
(1, 2, 3, 4)
Python makes no guarantees about the security of this second o
Pass it to eval:
>>> eval('(1, 2, 3, 4, 5)')
(1, 2, 3, 4, 5)
Basically what you are doing it evaluating the repr of the tuple.

In [1]: b = '(1,2,3,4)'
In [2]: b[1:-1]
Out[2]: '1,2,3,4'
In [3]: b[1:-1].split(',')
Out[3]: ['1', '2', '3', '4']
In [4]: tuple(b[1:-1].split(','))
Out[4]: ('1', '2', '3', '4')
Ooops,
how do I convert
b is a string b = '(1,2,3,4)' to b = (1,2,3,4)
