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 ValueError("Badly formatted string (missing brackets).")
items = s[1:-1] # removes the leading and trailing brackets
items = items.split(',')
L = [int(x.strip()) for x in items] # clean up spaces, convert to ints
return tuple(L)
For real production code, you will probably want better error checking.
