看到朋友们都很在关注这个内容，我花了一上午改进了一下代码，更加优雅一些，也更建议这样使用，当然是自己琢磨的啦！！！

使用
from 监控按键 import 快捷键
@快捷键("c")
def 第三个函数():
print("我按下了c")
@快捷键("ctrl", "v")
def 第三个函数():
print("粘贴")
@快捷键("a", "b", "c", "d", "e")
def 第三个函数():
print("dadadadad")

安装：pip install pynput
话不多说直接上代码：
from import Listener
import time
def on_press(key):
pass
def on_release(key):
all_key.append(str(key))
print(all_key)
if "'r'" in all_key:
print("开大招了")
all_key.clear()
if "'q'" in all_key:
print("开q技能了")
all_key.clear()
if "'w'" in all_key:
print("开w技能了")
all_key.clear()
if "'e'" in all_key:
print("开e技能了")
all_key.clear()
if 'Key.ctrl_l' in all_key and "'c'" in all_key: # ctrl+c
print('这是复制键')
all_key.clear()
if 'Key.ctrl_l' in all_key and "'v'" in all_key: # ctrl+v
print('这是粘贴键')
all_key.clear()
try:
if all_key[-1] == 'Key.ctrl_l':
time1 = ()
while True:
if () - time1 >= 1:
all_key.clear()
break
except:
pass
# if key == : # 停止监听
# return Falseurn False
def start_listen():
with Listener(on_press=None, on_release=on_release) as listener:
()
if __name__ == '__main__':
all_key = []
start_listen()
基本思路
每当按下一个按键后，会将按下的按键名称添加进特定的列表all_key中，从而根据列表里面的元素进行判断，若符合则证明“按下了特定的按键”，从而执行想要执行的函数。
缺点
程序中有一个all_key.clear()函数，是清除列表的所有元素，那么什么时候清除是一个问题。比如我按下了Ctrl键，那么’Key.ctrl_l’元素就会添加进去，但是我过了一会儿再按下c键，这时程序就会根据列表中有’Key.ctrl_l’和’c’从而认为我们按下了复制快捷键，可是我们并没有按下Ctrl+c。
我在想根据元素添加的时间来判断，比如检测到列表中有’Key.ctrl_l’元素，过0.5秒后再进行检测看有没有‘c’元素，如果有则证明按下了复制快捷键，如果没有检测到‘c’那么就执行all_key.clear()函数。
总之什么时候执行all_key.clear()函数是需要解决的问题
