Submission Question 1: Implementation of Overloading/Overriding

Problem

Develop a script to demonstrate an understanding of the overload (overwrite) methods of using Python operators. This lesson will focus on the "+" operator and the "__add__" method.

The program must have the following:

• Demonstration of an understanding of how to use the + operator for basic addition of two integer numbers

• Demonstration of an understanding of how to use the + operator for a concatenation of lists

• Demonstration of an understanding of how to use the + operator for a concatenation of strings

• Demonstration of an understanding of how to overload the __add__ method

Solving the Problem:

Step 1

Create a basic set of Python commands to demonstrate the addition of two integer numbers, and display the results in the operator interface window in PyCharm.

Step 2

Next, review the first example of an overloaded operator. In Python, the __add__ method that is being used to sum the two integer numbers above can also accept a list of numbers and concatenate them.

Step 3

Now, review the second example of an overloaded operator. In Python, the __add__ method that is being used to sum the two integer numbers above can also accept two strings and concatenate them.

Step 4

Lastly, overload the __add__ method, the method that has been used to sum two numbers, combine lists, and concatenate strings. Overload the
