Yes and no. The primary use case for __new__ was to allow subclassing of
immutable types. array.array is not immutable, but it's still a special
case, in that it enforce typ
Hmm ... I'm definitely not a python wizard, but it seems to be quite a

Has anyone seen a PEP on this subject ?

Nope. Obviously, array.array doesn't respect the usual rules.

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

from array import array
class Vector(array):
def __init__(self,size):
print "pouet"
array.__init__('f')
print "pouet"
v = Vector('c')
print repr(v)
will output :
pouet
pouet

Hi there.
I'm trying to create a simple class called Vector which inherit from
array.
class Vector(array):
def __init__(self,length):
"""initialize a vector of random floats of size length. floats
are in interval [0;1]"""
array.__init_
