Thanks for this! I wrote a simple OO wrapper using it as a base. https://github.com/markfickett/minecraftstatus/blob/master/mcstatus.py

Thanks for this! I used the *_varint functions to create a simple chat client.

Used this in in a load balancer for Minecraft.

using it for 1.13 server :D ty so much 👍

This is working for newer versions?

Great stuff, thanks a lot

There is an error for me:

The script is written for python2, so it doesn't work with python3.

I cannot really edit the code so it will work at python3 for some reason... so yeah

I've updated this to be compatible with python3
