+## Mojo TCP Socket Server with PythonInterface
+
+Let's do some things for a WEB with Mojo🔥.
+We do not have Internet access at playground.modular.com
+But we can steal do some interesting stuff like TCP on one machine.
+
+Let's write the first TCP client-server code in Mojo🔥 with [PythonInterface](https://docs.modular.com/mojo/MojoPython/PythonInterface.html)
