在上述示例代码中,我们首先导入了keyboard模块,并定义了一个main函数。然后,我们使用add_hotkey函数注册了一个热键,当用户按下了’q’键时,将会执行lambda: exit(0)这个匿名函数来停止脚本的执行。最后,我们使用wait函数来持续监听键盘输入,直到用户按下了注册的热键。 总结 通过使用keypress模块或keyboard模块,我们可...

Wait for a keypress: ch = getch() This works like you'd expect, except that it returns a string. You can also pause with the standard 'Press any key to continue. . . ' message: pause() Or pause with a custom message: pause('Press any key to exit.') You can have Python exit...

之后,调用pygame.event.get()获取事件队列中的任何KEYUP事件的列表。如果按键事件是 Esc 键的话,那么程序也会在这种情况下终止。否则,checkForKeyPress()函数将从pygame.event.get()返回的列表中返回第一个按键事件对象。 开始屏幕 def showStartScreen():titleFont = pygame.font.Font('freesansbold.ttf', 100...
