Q1. What is an abstract class?

An abstract class is a name for any class from which you can instantiate an object.
Abstract classes must be redefined any time an object is instantiated from them
Abstract classes must inherit from concrete classes.
An abstract class exists only so that other "concrete" classes can inherit from the abstract class.

Static methods can access and modify the state of a class or an instance of a class.

Q5. What are attributes?

Attributes are long-form version of an "if/else" statement, used when testing for equality between objects.

Q30. Assuming the node is in a singly linked list, what is the runtime complexity of searching for a specific node within a singly linked list?

The runtime is O(n) because in the worst case, the node you are searching for is the last node, and every node in the linked list must be visited.
The runtime is O(nk), with n representing the number of nodes and k representing the amount of time it takes to access each node in memory.
The runtime cannot be determined unless you know how many nodes are in the singly linked list.
The runtime is O(1) because you can index directly to a node in a singly linked list.

Q46. What does a class's init() method do?

The __init_method makes classes aware of each other if more than one class is defined in a single code file.
The _init_method is included to preserve backward compatibility from Python 3 to Python 2, but no longer needs to be used in Python 3.
The __init__() method is a constructor method that is called automatically whenever a new object is created from a class. It sets the initial state of a new object.
The __init__ method initializes any imports you may have included at the top of your file.

Q51. What is the purpose of the self keyword when defining or calling methods on an instance of an object?

self refers to the class that was inherited from to create the object using self.

self means that no other arguments are required to be passed into the method.
self refers to the instance whose method was called.

Q52. What is a class method?

A class method is a regular function that belongs to a class, but it must return None.
Class methods can modify the state of the class, but they can't directly modify the state of an instance that inherits from that class.
A class method is similar to a regular function, but a class method doesn't take any arguments.
Class methods hold all of the data for a particular class.

Q53. What does it mean for a function to have linear runtime?

You did not use very many advanced computer programming concepts in your code.
