i dont understand why you call incre()(is that a function call?)  the
one you are doing is something like
a = 0
print a
0

I think you like to do something like this

>>> def make_incrementor (n): return lambda x: x + n
>>>
>>> f = make_incrementor(2)
>>> g = make_incrementor(6)
>>>
>>> print f(42), g(42)
44 48
>>>
>>> print make_incrementor(22)(33)
55
