Mouvement Snake (The game)

[Catif]

Hi !
(sorry for my bad English I'm French)

I'm beginning in python, and I want to create my own game of Snake.
BUT I have a little problem, I don't know how to move like a snake.
In the Original Game the snake move all the 1s but in python I don't know how wait 1s and if the user don't tell which movement if he wants, the snake go away.

For the moment I just create a map and a choice GUI.


I'm in Windows OS on Python 3.9 64bit
