Double underscore before a name
The leading double underscore tells the Python interpreter to rewrite the name in order to avoid conflict in a subclass. Interpreter changes variable name with class extension and that feature known as the Mangling.
Python3
class Myclass(): def __init__(self): self.__variable = 10 |
