Class Foo:
def __init__(self):
self.__im_private()
def bar(self):
print('baz')
def __im_private(self):
print('back off, I can only be called by the class')

- probinso 10y agoEncapsulation in object oriented programming is a term we use to describe joining of conceptual topics. A class generally models a conceptual topic, the data and methods on the class allow a clean interface to operations from that topic. This extends the idea that 'the existence of a public method acts a documentation for what you can do with a object`. The existence of private methods and data are only to the benefit of the developer of the class. Python's standards for encapsulation are a little different, because you cannot hide methods and data the same way you would with other languages. This is made apparent with public interfaces to private methods like in .__iter__(self): methods.
