Python Exercises 43

1. Write a Python program named LastnameFirstname10.py, using your last name and your first name, that does the following:

• Create a print_menu function that will print out the available commands that the user can enter in order to carry out one of the following tasks: add an entry, find an entry, delete an entry, print all entries, or exit the program. (See Example Output)
• In the main function:
  • Create an empty list.
  • Explain to the user what your program does, and ask them to create a title for their list.
  • Call the print_menu function and ask the user what they would like to do.
  • If the user chooses to add / find / delete / print, then carry out the appropriate action:
    • If the user wants to add an entry, ask them for input and add it to the list.
    • If the user wants to find an entry, tell the user how many items are currently in the list, then ask the user which number item on the list they'd like to print.
      • For example, if the user says says they want to print their #2 favorite item, make sure to print the 2nd item on the list.
    • If the user wants to delete an entry, use a loop to print out the list and ask the user which entry they'd like to remove.
      • If the entry is not in the list, the function will throw an error. Use try-except to deal with this! (See Example Output)
      • If the entry is in the list, delete it and print the list again to confirm the change to the user.
    • If the user wants to print all entries, print a title for the list using the user's name and the number of entries. Then use a loop to print out a list of the user's favorite things.
  • Use a loop so the user can continuously add/find/delete/print until they decide to exit the program.
  • If the user chooses to exit, then end the program.
• All code in your program must be inside of a function definition, aside from calling main.
• You may only call main once.

2. Be sure to add comments for each section of your code.

3. Your output must be descriptive. Make sure it's clear to the user what your program is doing.

4. Your program should not use code/concepts we have not yet covered. You must demonstrate that you have mastered the concepts covered in class.

5. Remember to always begin your code with the following documentation comments.
