Python中的按键 [英] Key Presses in Python

问题描述

是否有可能使系统似乎已按下某个键，例如，我需要多次按下 A 键，这样做很费时间手动，我想写点东西来帮我做，而我所知道的唯一的东西就是Python.

Is it possible to make it appear to a system that a key was pressed, for example I need to make A key be pressed thousands of times, and it is much to time consuming to do it manually, I would like to write something to do it for me, and the only thing I know well enough is Python.

一种更好的表达方式，我需要模拟一个按键，即没有捕获按键.

A better way to put it, I need to emulate a key press, I.E. not capture a key press.

更多信息(根据要求): 我正在运行Windows XP，需要将密钥发送到另一个应用程序.

More Info (as requested): I am running windows XP and need to send the keys to another application.

推荐答案

安装 pywin32 扩展.然后，您可以执行以下操作:

Install the pywin32 extensions. Then you can do the following:

import win32com.client as comclt
wsh= comclt.Dispatch("WScript.Shell")
wsh.AppActivate("Notepad") # select another application
wsh.SendKeys("a") # send the keys you want

搜索WScript.Shell对象的文档(我相信在所有Windows XP安装中默认都安装了该文档).您可以在此处开始.

Search for documentation of the WScript.Shell object (I believe installed by default in all Windows XP installations). You can start here, perhaps.

编辑:发送F11

import win32com.client as comctl
wsh = comctl.Dispatch("WScript.Shell")

# Google Chrome window title
wsh.AppActivate("icanhazip.com")
wsh.SendKeys("{F11}")
