Yellowstone Codera

Yellowstone Codera is 14 days of Python puzzles inspired by Yellowstone National Park. Each puzzle highlights a different Python programming technique or library, though you don’t have to use Python to solve the puzzles. Most of the solutions have fewer than 30 lines of code.

• I will update this homepage each day with a new link to a new puzzle.
• When you enter the correct answer for a puzzle, the badge appears on the map.
• Answers are case-sensitive.
• Your answers are stored in local storage, so that when you update the page, your previous answers still appear. There is a link to delete all the local storage values on the homepage.
• The homepage was tested on Chrome.

Each puzzle contains a few files:

• story: Describes the puzzle.
• input: The input for the puzzle. (Not all puzzles have a separate input file.)
• test: A second input file for the puzzle that you can use to check your solution. (Not all puzzles have a separate test file.)
• hints: Links to libraries and functions that might help you solve the puzzle. The hints file does not have algorithmic hints.

I will post solutions to all the problems on the 15th day.
