This is a great initiative to help people understand how TCP works.

But an "implementing TCP in <an easy, readable language such as Python>" would be so much better IMHO. Rust is good, but not as readable pseudo-code to understand a concept.

As someone who programs both Python and Rust I found the Rust version very clear. And I would not use Python for this kind of programming.
