KeyDetector+detect_key() : boolUserInterface+show_result(result: str) 2.4 主要功能 检测按键状态:KeyDetector类负责检测按键状态,返回按键是否按下的布尔值。 显示检测结果:UserInterface类负责显示检测结果,可以在终端或GUI界面中显示检测结果。 3. 代码示例 3.1 按键检测模块 importRPi.GPIOasGPIOclassKeyDetector...
9. 在这段代码中,我们通过判断key的值来确定按下了哪个键,并执行相应的操作。 示例代码 下面是完整的示例代码: frompynput.keyboardimportListener,Keydefon_press(key):ifkey==Key.space:print('Space key pressed')elifkey==Key.esc:print('Esc key pressed')elifkey==Key.enter:print('Enter key pressed'...

然后在代码中使用它,例如: import keyboard # using module keyboard while True: # making a loop try: # used try so that if user pressed other than the given key error will not be shown if keyboard.is_pressed('q'): # if key 'q' is pressed print('You Pressed A Key!') break # fini...
首先,我们调用pygame库写一个获取按键的程序KeyPressModule.py import pygame def init(): pygame.init() win = pygame.display.set_mode((400, 400)) def getKey(keyName): ans = False for eve in pygame.event.get(): pass keyInput = pygame.key.get_pressed() ...

You can use play.key_is_pressed() to detect keypresses.In the code below, pressing the arrow keys or w/a/s/d will make the cat go in the desired direction.cat = play.new_text('=^.^=') @play.repeat_forever def do(): if play.key_is_pressed('up', 'w'): cat.y += 15 ...
