2、下载安装包：

图 3选择版本

图 4选择离线安装版本

可能有人看到windows 几个版本，对几个版本有迷惑的地方，解释

文字解释：

An executable installer hasevery component of the program you're installing locally in theinstaller itself. This means that you can download the installer on a computer with internet access, copy it over to acomputer without internet access and install it there. This is usefull ifyou're installing network card drivers.

Web-based installers are small programs that when you start them, they download thenessecary files and install themdirectly. This means that the installer is very small.

If you just want to install python on yourlocal computer with web-access, it doesn't really matter which one you pick.

本地安装过程：

图 12安装时，第五界面

注：

Clicking the "Disable pathlength limit" option removes the limitation on the MAX_PATH variable

看来这个选项，我理解错误，点击这个选项，是删除path里MAX_PATH变量
