Hello CheckiO users! 🙂

Last week we had new three very simple missions. Today's leaderboard should be opened, so check the best solution for those missions.

Also, we had Python 3.10 release, but without scipy, but is fixed now.

Challenge yourself with our missions

Unique Email Addresses - (a very easy mission) Given an array of strings - valid emails, return the number of unique emails.

delivery_drone([0, 2, 0]) == 4
delivery_drone([0, 0, 1, 2]) == 6

💡 3 Highlights from the Python world:

Mastering Structural Pattern Matching - Anatomy of the Pattern Matcher Syntax The match statement

Project: Command-Line To-Do App With Python and Typer - In this tutorial, you’ll build a functional to-do application for the command line using Python and Typer, which is a relatively young library for creating powerful command-line interface (CLI) applications in almost no time.

Cython, Rust, and more: choosing a language for Python extensions - Different situations require different approaches. So don’t just pick the tool you’re most familiar with—though you should definitely take that into account in your decision!

The users who’ve made the TOP 3 this month are mivireactor257, amvasiliev80, and Alex_4444D.You are doing great, guys! Keep on coding! 👏🏼
