我如何创建一个定期输入键盘和鼠标输入的程序？

Question

我想要一个满足以下要求的程序：

• 按键盘x终止程序
• 按键盘y暂停或取消暂停程序
• 虽然“暂停”该程序未输入键盘或鼠标数据
• 虽然“不暂停”程序会定期触发程序生成的键盘和鼠标事件。

keyboard.add_hotkey（'y'，self.toggle）keyboard.add_hotkey（'x'，sys.exit）

本文最后是我到目前为止的代码。当前，

• 程序始终处于“暂停”状态
• 按键盘键'x'无法终止程序
• 按键盘键'y'无法暂停或取消暂停程序

可以像这样安装第三方库keyboard和mouse：

[path to python]\Python38-32\python.exe -m pip install keyboard --user
[path to python]\Python38-32\python.exe -m pip install mouse --user

CODE：

Answer 1

我添加了print('toggle')和print('unpaused')以查看它们是否已执行并且它们不显示文本。

当我删除带有sys.exit的行时，我可以看到文本。

如果我创建运行self.exit并使用sys.exit()的add_hotkey('x', self.exit)，那么我仍然可以看到文本。

---

[另一个问题是，即使代码为for func in self._it:分配了不同的迭代器，_it也始终使用首次迭代器self._it。暂停/未暂停的设置break

时，我使用self.change_it = True退出此循环

    def go(self):
        while True:
            for func in self._it:
                func()
                if self.change_it:
                    break
            self.change_it = False

    def unpause(self):
        print('unpaused')
        self._it = itertools.cycle(type(self).IT_1)
        self._state = "unpaused"
        self.change_it = True

    def pause(self):
        print('paused')
        self._it = itertools.cycle(type(self).IT_2)
        self._state = "paused"
        self.change_it = True

---

sys.exit（）也会出现问题，它会停止侦听器，并且x，y，e会停止工作，但不会停止循环for func in self._it:，并且会一直工作。我在上一个while run_loop:中使用while True代替了go()，所以我可以使用self.run_loop = False和self.change_it = True]退出此循环

    def go(self):
        self.run_loop = True
        while self.run_loop:
            for func in self._it:
                func()
                if self.change_it:
                    break
            self.change_it = False

    def exit(self):
        print('exit')
        self.run_loop = False
        self.change_it = True
        sys.exit()
另一个问题是您在某些*，**中忘记了*args和**kwargs
