pywinauto教程2

一、环境安装

1.命令行安装方法

pip install pywinauto==0.6.7

2.手动安装方法

安装包下载链接：
pyWin32: python调用windows api的库
https://sourceforge.net/projects/pywin32/files/pywin32/Build 220/

comtypes： COM接口的调度https://github.com/enthought/comtypes/releases

six: 用来兼容Python2和Python3的库
https://pypi.org/project/six/

Pillow：可选，用来做屏幕截图的
https://pypi.org/project/Pillow/2.7.0/

Pywinauto：PC端自动化工具
https://github.com/pywinauto/pywinauto/releases

解压缩后执行 python setup.py install
注：建议使用第一种命令行安装，方便。

3.环境检查

命令行中打开python解释器，运行以下代码，windows自带的记事本会被启动，若无报错，则证明pywinauto已安装成功。

1 2	from pywinauto.application import Application app = Application(backend="uia").start("notepad.exe")

二、封装函数

# -*- coding: utf-8 -*-
import time,os
from pywinauto import application
