Python List methods -

i had make text processing in python.

so created class textprocessing:

manipulator = textprocessing("one 2 3 4 four") repr(manipulator) => "one 2 3 4 four" manipulator["four"]  //=> [3, 4] => made list 

but after had make function that:

manipulator.two.replace("second") => "one second 3 4 four" 

i have no idea how link 2 here list.

you can play overriding __getattr__

class a(object):     def __init__(self, s):         self.s = s     def replace(self, x):         self.s = self.s.replace(self.x, x)     def __getattr__(self, name):         self.x = name         return self  = a('abc') a.b.replace('x') print a.s 

or

class b(object):     def __init__(self, x, y):         self.x = x         self.y = y     def replace(self, x):         self.x.s = self.x.s.replace(self.y, x) class a(object):     def __init__(self, s):         self.s = s     def __getattr__(self, name):         return b(self, name)  = a('abc') a.b.replace('x') print a.s
