If you don't want to rely on third party libraries, and want a human-readable
format I'll suggest using csv file format :
and this way ?
In [47]: class Z(object) :
....: def __init__(self, val) : self.val = val
....:
....:
In [48]: lst = [Z(i) for i in range(2) + [ str(e) for e in range(2) ] ]
In [49]: [ (e, e.val) for e in lst ]
Out[49]:
[(<__main__.Z object at 0xa76c252c>, 0),
(<__main__.Z object at 0xa76c27ac>, 1),
(<__main__.Z object at 0xa76c23ac>, '0'),
(<__main__.Z object at 0xa76c23ec>, '1')]
In [51]: csv.writer(file('config.csv', 'w')).writerows([
(type(i.val).__name__, i.val) for i in lst])
In [52]: print file('config.csv').read()
int,0
int,1
str,0
str,1
In [53]: l = [ Z(eval(class_)(val)) for class_, val in
csv.reader(file('config.csv')) ]
In [54]: [ (e, e.val) for e in l ]
Out[54]:
[(<__main__.Z object at 0xa76c218c>, 0),
(<__main__.Z object at 0xa76c260c>, 1),
(<__main__.Z object at 0xa76c256c>, '0'),
(<__main__.Z object at 0xa76c25cc>, '1')]
