Parse a tuple from a string?

by

It already exists!

>>> from ast import literal_eval as make_tuple
>>> make_tuple("(1,2,3,4,5)")
(1, 2, 3, 4, 5)

Be aware of the corner-case, though:

>>> make_tuple("(1)")
1
>>> make_tuple("(1,)")
(1,)

If your input format works different than Python here, you need to handle that case separately or use another method like tuple(int(x) for x in tup_string[1:-1].split(',')).
