I can't make the restart button
please help me, please, I want to make a reset button in my project, but I do not know how, I want, provided that when I press r, all these games are reset, that is, if I have a record of 1500 and press r so that the record becomes 0 again, the project tetris works with pygame, if I need the code, I can throw it off when R is pressed. Call a function that resets all variables to their default values.
