There is an example of code in Python documentation as follows:
def init(self, iterable):
self.items_list = 
def update(self, iterable):
for item in iterable:
__update = update #private copy of original update () method
In the last line of code is the comment #private copy of original update(). According to the literature, this is supposed to create a private copy of the update method in the base class in case an update method is created in a sub class.
Does anyone have any insight on the significance of doing this?
