Question

The concept of public and private class members is part of an approach called object oriented programming. This approach is relevant to many different programming languages and each implements and supports it in slightly different ways. Which of the following sentences are correct about public and private as implemented in python?

  1. Python does not support the concepts of public and private members of a class.
  2. Python does not directly enforce public and private member access and so will not generate an error if you fail to respect the convention.
  3. Just like other languages that support Object Oriented Programming, such as C++ and Java, Python strictly enforces the concept of public and private class members and will generate an error when it runs if you try to access a private member from outside of the class.
  4. Python supports the concept of public and private through convention - by adding an underscore '_' at the beginning of the member function or variable.
