This will use 100% of your CPU until you press the key.# 不要使用下面的代码, 它会占用100%的CPU##while not keyboard.is_pressed('space'):# continue#print('space was pressed, continuing...')# Do this instead# 改成下面的代码keyboard.wait('space')print('space was pressed, continuing......
我们在代码前后添加注释以便于理解: # Output a welcome messageprint("欢迎使用Press Any Key To Continue!")# Pause and wait for the user to press any keyinput("按任意键继续...") 1. 2. 3. 4. 5. 步骤4: 运行代码并测试效果 将代码放在一个.py文件中,然后通过终端运行。你应该会看到显示的消...
