Public members are accessible from outside the class as they have no access restrictions. Private members (c) are accessible only within the class. Protected members (d) are restricted to the class and its subclasses. Secured (a) is not a standard access modifier keyword in object-oriented terminology.

In Python, 'continue', 'break', and 'while' are reserved keywords used for control flow. 'operator' is not a reserved keyword in Python; it is the name of a standard library module.

Subroutines (also known as functions) are small, reusable sections of code designed to perform a specific task. Pseudo code is a high-level description of an algorithm, modules are files containing code, and files are data storage entities.

Python generally classifies control structures into 3 main types: Sequential, Selection (or Branching), and Iteration (or Looping).

In Python (and many other object-oriented languages), the dot operator (.) is used to access the attributes and methods of a class object.
