Question

Write a Python program that stores the data for each player on the team, and it also lets the manager set a starting lineup for each game.

Questions:

- 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.

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