Solution
-
The correct answer is C) A collection of related functions and variables that can be reused in other programs. In Python, a class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods).
-
The correct answer is A) To define the instance variables for a class. The init() method in Python is a special method that is automatically called when an object of a class is created. It helps to set initial values to the object attributes.
-
The correct answer is C) Using the class name followed by parentheses. In Python, you can create an instance of a class by calling the class using its name followed by parentheses. For example, if you have a class named 'MyClass', you can create an instance of this class by using 'MyClass()'.
