Private attributes in python are intended to be accessed and modified only within the class where they are defined.
However, Python provides a mechanism called name mangling that allows you to access private attributes from outside the class, although it is generally discouraged.
Name mangling modifies the name of the private attribute by adding a prefix of
_ClassName to it, where
ClassName is the name of the class. Here’s an example of how to access private attributes using name mangling:
class MyClass: def __init__(self): self.__private_var = 20 # Private attribute def __private_method(self): print("This is a private method") obj = MyClass() # Accessing private attribute using name mangling print(obj._MyClass__private_var) # Output: 20 # Accessing private method using name mangling obj._MyClass__private_method() # Output: This is a private method
In the above example, we access the private attribute
__private_var and the private method
__private_method using the name mangling syntax
However, it’s important to note that accessing private attributes directly from outside the class is generally discouraged and goes against the principle of encapsulation. Private attributes are intended for internal use within the class to ensure data protection and maintain class integrity.
