slither | slither.io imitation | Game Engine library

I have programmed a simple clone of Slither.io in python using pygame and sockets and I have three problems:

1. When I play the game alone on my laptop the game is choppy. Every ten seconds my game get stuck for a while (one milisecond) and then continue. It's not a big problem but it's annoying.
2. When I play on two computers in my local network, I see the other player (the other snake) is also choppy.
3. The strangest problem is when I run my server on my main laptop and then run the game on my second laptop the game starts and after few seconds crash. Debugger on client says that pickle data was truncated while receiving data from the server. But when I run the server program on my second laptop and the game on my main laptop everything is OK. Why?

I tried:
Problem 1. change FPS on the client and time.sleep on the server
Problem 2. change time.sleep on the server
Problem 3. change the input value of recv() method

Server code:

Python version: 3.8.5 Solc version: 0.7.0+commit.9e61f92b.Linux.g++ Slither version: 0.6.13

When trying to run slither . on a solidity contract I get the following stack trace:

Essentially when the browser window goes larger thh div stays centered and creates white space on the outside. I want the same thing to happen when the browser window goes smaller. I want to see less of the div but keep it centered. At the moment I see less of the div but the left side locks so I end up only seeing a slither of the left part of the image (instead of the center). Sorry if this is a convoluted way of asking I am new to programming. Any help would be massively appreciated! Thanks in advance! :)

p.s I am also struggling to have the video playing if anyone can help with that too

Here is my code currently

Am trying to show the 'You loose like the looser you are looser' text after the small moving rectangle hits the bounderies... but instead, the rectangle is moving past the bounderies and the 'You loose' text only shows up after i hit a random button... the code is below

As an exercise, I am trying to create my own bind() function using apply() and prototypal inheritance that I have just learned.

This is my code:

Based on the typescript docs https://www.typescriptlang.org/docs/handbook/classes.html, here's an example of simple inheritance:

I'm writing this program to become comfortable with types (not objects!).

The basic premise is the user enters an animal name (cow, snake bird), then an action (eat, move, sound.) My code then looks it up and returns the value.

So, the user entry is suppose to be on ONE line separated by a " ". I use strings.Split.

I'm getting a "panic" notice when the user only enters a single char. I'm thinking this panic arises out of the compiler trying to "split" a single char.

TWO Questions: 1. Am I right? 2. How do I fix it?

Here is my code
