Python, __init__ and self confusion

Question

Alright, so I was taking a look at some source when I came across this:

>>> def __parse(self, filename):
...         \"parse ID3v1.0 tags from MP3 f         


        

Answer 1

Functions/methods can be written outside of a class and then used for a technique in Python called monkeypatching:

class C(object):
  def __init__(self):
    self.foo = 'bar'

def __output(self):
  print self.foo

C.output = __output
c = C()
c.output()
