recursion in Class-methods?

[defn noob]

class Graph(object):

where does anyone write like that? I've seen only examples like i have
written.

is the object then passed to init?


class Graph(object):
    def __init__(self, dictionary):
        self.structure = dictionary

or

class Graph(object):
    def __init__(self, object):
        self.structure = object


i dont get it.




and "mutable containers", do you refer to "path=[]" as a parameter.
