What this room is for

Serpens is a public room that teaches Python. A visitor can read where the language came from, how it sits beside Rust, JavaScript, and Java, and why engineers reach for it. The first page is a short path: the shape of a tiny program, the syntax that writes it, and names, shared objects, None, and exceptions. /further continues on its own page with duck typing, modules, comprehensions, closures, threads, and async.

Checks are graded in the browser. A program runs only when the visitor chooses Try it, and then on Python Tutor. This site does not run an interpreter and does not keep an account.

The name of the product is Serpens.
