Create a frame and assign callbacks to event handlers

frame = simplegui.create_frame("Home", 500, 800 ) frame.set_canvas_background('white')

frame.add_button(u"我猜", ai_guess_handler)

obj_ai_input = frame.add_input(u"输入你的数字[0,1000]让电脑猜猜",ai_input_handler,50) timer = simplegui.create_timer(600,timer_handler)

frame.add_button(u"回车或者点击此处开始", ai_handler) frame.add_button(u"回放", review_handler) frame.set_draw_handler(draw)

Start the frame animation

frame.start()
