class MyClass:
    def __init__(self):
        self._protected_variable = 10
    
    def _protected_method(self):
        pass

__ :

• private variable/method
• iska matlab hai ye strictly private hai, ye bilkul bhi class se bahar accessible nahi hona chahiye
• example,

self.__private_variable

• more,

class MyClass:
    def __init__(self):
        self.__private_variable = 20
    
    def __private_method(self):
        pass

Thanks.
