Constructor documentation assigned to class or __init__?

[Leif K-Brooks]

Should a class's constructor be documented in the class's docstring or
__init__'s docstring? For instance:

class Foo(object):
"""This class represents mating lizards. Constructor requires one
argument, the lizard this lizard is mating with."""
def __init__(self, other):
pass

# or

class Bar(object):
""This class represents mating lizards."""
def __init__(self, other):
"""Initiate the object. Requires one argument, "other", which is the
lizard this lizard is mating with."""
pass

Think as a user of your library: Where will you look at if you do not
know how to use a class ?

It's probably a matter of taste, but
I'd prefer the style like in class Bar, because
information about the constructor is technically
nearer to the constructor.
Please don't write "Initiate the object." That's
what a constructor is (almost) always supposed to do.
