Nicely done!
Here are some thoughts for further improvement:

• Minor: you're missing a space after = in line 11.
• How can you give the user a useful error message if they enters an invalid selection e.g. "z"?
• How can you make your design scalable and maintainable? e.g. easily allow for changing the price or name of a candy, easily allow adding 4 more candy choices etc.
• As you learn more in chapters to follow, consider if using a data structure like a hash would allow you to better organize your data and make your design more scalable.
