Thank you for your contribution!
- It is always intriguing to try and solve puzzles with coding. Thumbs up for that!
- A short intro about the puzzle itself would have helped, in addition to the link to the puzzle original source. It disrupts the reader a bit.
- I liked how low level your explanations were. Very helpful for starters.
- A short description about the results prior to displaying your output would have been helpful as well.
- You had few minor typos across your text. Titles could have been slightly more elaborate, such as your use of just findall and Sets.
Overall, good job!
