一.安装selenium 1.在终端通过命令安装 pip3 install -U selenium 二.准备环境 1.在电脑中安装谷歌浏览器chrom，和下载估计浏览器驱动chromdriver,以下附上驱动下载地址 驱动下载地址： http://npm.taobao.org/mirrors/chromedriver/ 注意：浏览器驱动下载一定要与安装的浏览器版本匹配 查看浏览器版本： 三.将下载的驱动文件放到Python的安装目录下，由于我的电脑上装的Python3.7,所以我通过在终端输入命令先找出Python3.7的安装路径 1.终端输入命令： 2.然后点击 访达-前往-电脑-资源库-Framework-Python.framewrok-Versions/3.7/bin/python3.7/bin 目录下，一定要放在这个目录下，要不然在Pycharm中启动不成功 3. 查看环境搭建是否成功 from selenium import webdriverdriver = webdriver.Chrome()driver.get("http://www.baidu.com")如果能够成功启动谷歌浏览器打开百度首页，即成功。 来源： https://www.cnblogs.com/wswnm/p/11851334.html

Please focus on the fact that it doesn't work and not why you would be doing this in the first place, it is purely a theoretical question about a technical exercise. This is a rather weird one. I'm attempting to construct a variable variable using a string named $GLOBALS . From the global scope Let's see what we get when var_dump() ing this in the global scope. $g = sprintf('%s%s%s%s%s%s%s', chr(71), chr(76), chr(79), chr(66), chr(65), chr(76), chr(83));

I tried two methods: object.size(obj) save(obj, file = "obj.Rdata") and checking the file size. The .Rdata file is compressed so it was always smaller than what object.size() has returned, until I saw this object: > object.size(out) 144792 bytes > save(out, file = "out.Rdata") # the file has 211 759 bytes When I open the file in new R and run object.size(out) , it reports 144792 bytes again. Any idea how this can happen? I don't want to post the complete

I am not putting the whole code here, but for simplicity I am creating a mock file and mock program (given below) which behaves similarly at simplest level. In this mock program I am calculating, say
