Pygame typing game how to generate speed control letters?-CodePudding

Game description: the top of the screen down different letters, keyboard keys corresponding letter disappear, the letter x position are random, letter is gradually falling speed faster, if 10 letters at the bottom of the screen, the game ends, in order to simplify the game, Mr Into the same one letter (letters A, for example), has achieved, but the generated letters so quickly, how to add the code to control the rate of letters A generation? Seems to add time. Sleep (5) can make the letters whereabouts caton,

Make a thread to control the letters generated, sleep in the thread, so as not to cause the main interface caton,
