call a protected method on an instance of a class in python

In Python, to call a protected method on an instance of a class, you can use the following syntax:

main.py
instance._ClassName__methodName(parameters)
44 chars
2 lines

This syntax uses name mangling to access the protected method. When you define a method with a double underscore prefix in a class, its name gets mangled by the Python interpreter. The name is replaced with _ClassName__methodName, where ClassName is the name of the class where the method is defined.

Here is an example that shows how to call a protected method in Python:

main.py
class MyClass:
    def __init__(self):
        self.__count = 0

    def _increment_count(self):
        self.__count += 1

    def get_count(self):
        return self.__count

obj = MyClass()
obj._MyClass__increment_count()
print(obj.get_count())  # Output: 1
262 chars
14 lines

In this example, we define a class MyClass with a private variable __count and a protected method _increment_count. We create an instance of the class, call the protected method using the name mangling syntax, and then print the value of the private variable. The output will be 1.
