需求

基于pynput库开发一个脚本。

要能够用按键控制它启动，暂停。

简单实现

key参数，代表了用什么键控制。

state属性，代表了当前的开关状态。
listener属性，是pynput的监听器。

start方法，启动监听器。

from pynput import keyboard as kbclass Simple_Script():def __init__(self, key):self.key = keyself.state = Falseself.listener = kb.Listener(on_press=self.__a())def start(self):self.listener.start()def __a(self):def on_press(key):if key == self.key:self.state = not self.stateif self.state:print("启动", end="")else:print("暂停", end="")return on_press

测试代码

import time
from base.script import kb, Simple_Script
if __name__ == '__main__':a = Simple_Script(kb.Key.f12)a.start()i = 0while True:if a.state:print(i)i = i + 1time.sleep(1)

效果：

更新：添加两个方法

可以在启动，暂停时做一些事情。

from pynput import keyboard as kb
class Simple_Script():def __init__(self, key, fun1=None, fun2=None):self.key = keyself.state = Falseself.listener = kb.Listener(on_press=self.__a(fun1, fun2))def start(self):self.listener.start()def __a(self, fun1, fun2):def on_press(key):if key == self.key:self.state = not self.stateif self.state:print("启动", end="")if fun1 != None:fun1()else:print("暂停", end="")if fun2 != None:fun2()return on_press
