Question

Chapter 8 Python Case study Baseball Team Manager

For this case study, you’ll use the programming skills that you learn in Murach’s Python Programming to develop a program that helps a person manage a baseball team. This program stores the data for each player on the team, and it also lets the manager set a starting lineup for each game. After you read chapter 2, you can develop a simple program that calculates the batting average for a player. Then, after you complete most of the other chapters, you can enhance and improve this program.

***PLEASE I NEED THIS ASAP, ITS DUE MONDAY 07/08

Chapter 08: Handle exceptions

Thoroughly test the program and update it so it handles all exceptions that you encounter during testing.

******This is what the Professor had provided us and this screenshot is what the assignment should look like in IDLE.

Baseball Team Manager MENU OPTIONS 1 Display lineup 2 Add player 3 Remove player 4 Move player 5 Edit player position 6 Edit player stats 7 Exit program POSITIONS с, 1в, 2в, зв, ss, LF, сF, RF, P Team data file could not be found. You can create a new one if you want Menu option: 2 Name Mike Position: Ss At bats: 0 Hits: 0 Mike was added Menu option: X Not a valid option. Please try again. MENU OPTIONS 1 Display lineup 2 Add player 3 Remove player 4 Move player 5 Edit player position 6 Edit player stats 7 Exit program Menu option: 7 Bye!

Specifications

- Handle the exception that occurs if the program can’t find the data file.

- Handle the exceptions that occur if the user enters a string where an integer is expected.

- Handle the exception that occurs if the user enters zero for the number of at bats.

Here is what I currently have from previous assignments:
