How do you define instance variables in Python?

• By importing them from another module

• By defining them within a class using the self keyword

• By using the keyword 'instance'

• By defining them outside of any class

Explain the concept of Python classes.

• Python classes are a way to create new types of objects in Python.

• Python classes are used for mathematical calculations only.

• Python classes are a type of snake found in the wild.

• Python classes are a way to create new types of animals in Python.

What is the purpose of a class method?

• The purpose of a class method is to access instance variables directly

• The purpose of a class method is to modify class state and perform operations that are not specific to any particular instance.

• The purpose of a class method is to make the code more readable

• The purpose of a class method is to create new instances of the class

Give an example of defining a class method in Python.

• classmethod()

• staticmethod

• def method(self)

• @classmethod

What are instance variables in Python?

• Variables defined within a class but outside any of the class's methods

• Variables defined outside a class

• Variables defined within a module

• Variables defined within a function

How are instance variables different from class variables?

• Instance variables are shared among all instances of a class, while class variables are specific to each instance of the class.

• Instance variables and class variables are the same and can be used interchangeably.

• Instance variables are specific to each instance of a class, while class variables are shared among all instances of the class.

• Instance variables are not specific to each instance of a class, while class variables are shared among all instances of the class.

What are the characteristics of Python classes?

• Polymorphism, abstraction, and composition

• Variables, loops, and functions

• Attributes, methods, inheritance, and encapsulation

• Operators, data types, and control structures

How do you create an instance of a class in Python?

• ClassName{}

• create ClassName()

• ClassName()

• new ClassName()

What is the role of self in Python classes?

• Represents the instance of the class

• Represents the parent class

• Stores class methods

• Used for importing external modules

How many objects can be made from a class? 

• None, you make classes from objects
  
• one
• As many as you want
• All of the above
