**Q6** - Stripping Names: Store a person’s name, and include some whitespace characters at the beginning and end of the name. Make sure you use each character combination, "\t" and "\n", at least once. Print the name once, so the whitespace around the name is displayed. Then print the name after striping the white spaces.

...

### Day 3

**Date**: [2024-05-21]

- Print a new set of invitation messages, one for each person in your list.

**Q17** - Shrinking Guest List: You just found out that your new dinner table won’t arrive in time for the dinner, and you have space for only two guests.
- Start with your program from Exercise 16. Add a new line that prints a message saying that you can invite only two people for dinner.

- Remove guests from your list one at a time until only two names remain in your list. Each time you pop a name from your list, print a message to that person letting them know you’re sorry you can’t invite them to dinner.

- Print a message to each of the two people still on your list, letting them know they’re still invited.

- Remove the last two names from your list, so you have an empty list. Print your list to make sure you actually have an empty list at the end of your program.

Call show_magicians() with each array to show that you have one array of the original names and one array with the Great added to each magician’s name.

**Q44** - Sandwiches: Write a function that accepts a array of items a person wants on a sandwich. The function should have one parameter that collects as many items as the function call provides, and it should print a summary of the sandwich that is being ordered. Call the function three times, using a different number of arguments each time.

**Q45** - Cars: Write a function that stores information about a car in a Object. The function should always receive a manufacturer and a model name.
