How would you explain the importance of testing and debugging to someone who is just starting to learn Python? Share an example of the debugging of Python code $($different from your classmates$)$ that shows a specific test case that you used to determine that your code was working as expected. Use the main function to handle all of the input, processing, and output to the screen. Include screenshot$($s$)$ showing the output of your code. Use in$-$line comments to describe each $($detail the purpose of the test case, the variables you verified, and why you chose the test case$).$ Support your information by citing at least one reference, and remember to respond to at least one other students' posts by providing meaningful insight into the topic.
