Name mangling is helpful for letting subclasses override methods without
breaking intraclass method calls. For example::
- class Mapping:
- def __init__(self, iterable):
- self.items_list = []
- self.__update(iterable)
+ class Mapping:
+ def __init__(self, iterable):
+ self.items_list = []
+ self.__update(iterable)
- def update(self, iterable):
- for item in iterable:
- self.items_list.append(item)
+ def update(self, iterable):
+ for item in iterable:
+ self.items_list.append(item)
- __update = update # private copy of original update() method
+ __update = update # private copy of original update() method
- class MappingSubclass(Mapping):
+ class MappingSubclass(Mapping):
- def update(self, keys, values):
- # provides new signature for update()
- # but does not break __init__()
- for item in zip(keys, values):
- self.items_list.append(item)
+ def update(self, keys, values):
+ # provides new signature for update()
+ # but does not break __init__()
+ for item in zip(keys, values):
+ self.items_list.append(item)
Note that the mangling rules are designed mostly to avoid accidents; it still is
possible to access or modify a variable that is considered private. This can
