I can't move turtle in python which for snake game

I'm trying to make a snake game just for fun and learning but I can't move my turtle. When I add the border lines and run it. My turtle can't move a bit. Problem pop up when I add the "if turtle.xcor()>290 or turtle.xcor()<-290 or turtle.ycor()>290 or turtle.ycor()<-290:" border lines

I've checked the lines and searched on the internet but i couldn't find a solution. I'm new so the problem might be easy.

Snake turtle don't grow up

I'm beginner and I can't undertstand why my code doesn't work. I make snake game. My snake must grow but it doesn't. You can run the code in python interpreter and see how it works. And when I run a code, head of snake moves slower and slower. It isn't really good. I would be thankful for help. Python version is 3.10(probably it is also important)

move()

Your code has many problems.
You have wrong indentations. You move segments inside if head.distance(food) < 10: - so it moves it only once. You should do it in every loop.
You move segments after moving head - so segment has the same position as head. You should move segments before you get new position for head.
The biggest problem is that your snake moves smoothly using speed = 0.1 so when you create new segment then it may get position head + 0.1 and it displays one segment on another segment and you can't see segments. It would have to get position head + head_size. Maybe first try classic version where snake moves from square to square using speed = head_size
Another problem: in for-loop you get value from segments[i-1] and you set segment.goto(x, y) but it should be segments[i].goto(x, y)
Working example with classic snake which moves from square to square.

I can't get VSCode to open window for snake script

I am practicing some very simple projects and I found the snake game and handed to try my hand. I am pretty sure I copied the code completely but when I run it a small blue screen pops up for a split second and then disappears and doesn't say what's wrong.
site I am using for the project. https://www.geeksforgeeks.org/create-a-snake-game-using-turtle-in-python/

You are getting a blue screen because the code is not complete there are some variables missing + the main game loop doesn't exits so the game simply crashes here is the complete code I got it from the same website further down Full Code

Need a way to add teams and solo gameplay. Also any idea on making a main menu with tkinter for playing as team or solo

I'm new to programming and python. I somehow followed a guide and came up with a snake game. This game runs great. However, there are a few things that I need to add to make it much better.
First of all, I want to add some sort of start screen menu. Want it to have buttons. This start screen will tie into my next addition.
I am wanting to add a scoring system for teams or solo. I need it to selectable from the main screen. Like "play as a team" or "play on your own" buttons. If the team button is pressed then there will be 5 rounds, one round for each player. I have seen somewhat how to make the main menu screen using Tkinter. However, the other part about the teams and solo part seems to baffle me. Can't find a way to do it and can't find a guide online. I'm kinda stuck here.
Any help will be greatly needed and accepted. I will post the game code below so you guys can see it.
Thanks,
