A class's methods use 'self' to refer to the object (instance of the
class) they're being called on; mostly, they access (get or set)
attributes on self, and/or call other methods on self.
I hope that's English enough for you. Here's a simple example:
class Struggle(object):
def __init__(self, value): self.value = value
def __str__(self): return 'Struggle(%r)' % self.value
Class Struggle has two (special) methods, an initializer and a
transformer to string. Each uses 'self' to refer to the instance on
which it's being called -- specifically, to set or get the 'value'
attribute. So, when I code:
x = Struggle(23)
print x
I obtain the output:
Struggle(23)
In this case, the 'self' inside each method refers to the same object to
which the name 'x' refers ``on the outside''.
