此代码可以满足您的需求：

class menu:
    hover = False

    def __init__(self, text, pos, callback):
        self.text = text
        self.pos = pos
        self.callback = callback # so we now what function to call
        self.set_rect()
        self.draw()
    # the rest of your code

def quit_loop():
    global running
    running = False
select = [menu("Computer Virus", (100, 200), lambda: print("Computer Virus")), # Add a callback
          menu("Computer Crime", (100, 300), lambda: print("Computer Crime")),
          menu("QUIT", (100, 400), quit_loop)]

running = True
while running:
    for evnt in event.get():
        if evnt.type == QUIT:
            running = False
        if evnt.type == MOUSEBUTTONDOWN: # if a mousebutton got pressed
            if evnt.button == 1: # if the first button got pressed
                for menu in select:
                    if menu.rect.collidepoint(evnt.pos): # does this one collide
                        menu.callback() # call the callback
