Inherit from array

[TG]

Obviously, there is something I didn't catch in python's inheritance.

from array import array
class Vector(array):
    def __init__(self,size):
        print self.typecode
        array.__init__(self,'f')

>>> v = Vector('c')
c

Here, it says the typecode is 'c' - I thought such an information was
initalized during the array.__init__(self,'f') but obviously I was
wrong.

Maybe the typecode is defined before, during the call to __new__ method
... But here i'm getting lost.
