| 2 | +Exercise 33: Birthday Dictionaries |
| 3 | + |
| 4 | +This exercise is Part 1 of 4 of the birthday data exercise series. |
| 5 | +The other exercises are: Part 2, Part 3, and Part 4. |
| 6 | + |
| 7 | +For this exercise, we will keep track of when our friend’s birthdays |
| 8 | +are, and be able to find that information based on their name. |
| 9 | +Create a dictionary (in your file) of names and birthdays. When you |
| 10 | +run your program it should ask the user to enter a name, and return |
| 11 | +the birthday of that person back to them. The interaction should |
| 12 | +look something like this: |
| 13 | + |
| 14 | +>>> Welcome to the birthday dictionary. We know the birthdays of: |
| 15 | +Albert Einstein |
| 16 | +Benjamin Franklin |
| 17 | +Ada Lovelace |
| 18 | +>>> Who's birthday do you want to look up? |
| 19 | +Benjamin Franklin |
| 20 | +>>> Benjamin Franklin's birthday is 01/17/1706. |
| 21 | +Happy coding! |
