Well, not explicitly. If you're familiar with OOPS in C++, self is
analogous to the "this" pointer there. Also, you needn't call it self.
Writing something like
class A(object):
def __init__(me, name):
me.name = name
print "The name is %s"%me.name
will work fine as well.
The actual identifier 'self' is just a convention.

__init__ is not *a* constructor as much as it is *the* constructor
method. It is one of the many class methods that have special meanings.
If you want the entire list, try

__baba__ is not a special function so it will have no special
significance. It is treated as any other class method.
I believe the URL above has what you're looking for.
