https://repo.anaconda.com/archive/Anaconda2-2019.07-Windows-x86_64.exe 64bit for Python 2.7 version,使用IDM下载即可
https://repo.anaconda.com/archive/Anaconda3-2019.07-Windows-x86_64.exe 64bit for Python 3.7 version ,使用IDM下载即可
Anaconda3 没有开始菜单,参考:https://www.jianshu.com/p/beb59ca2b46e ?
一、安装 Anaconda2-2019.07-Windows-x86_64.exe
开始菜单
安装完成。已经自动安装了python 2.7.16
可以将 “D:PythonWorkAnaconda2” 目录添加到path中
二、再安装 python 3.7
开始菜单 --> 启动 Anaconda Prompt (Anaconda2)
运行命令:conda create -n python37 python=3.7
安装过程:

切到python 3.7 命令:conda activate python37
回到python 2.7 命令:conda deactivate
三、打开 python IDE工具
开始菜单 ---启动---> Spyder (Anaconda2)
主界面,默认使用的是 Python 2.7:
如何让 Spyder 使用Python 3.7 ?
方法步骤:
开始菜单 --> 启动 Anaconda Prompt (Anaconda2) ,然后依次运行如下命令:
1. 切到python 3.7 命令:conda activate python37
2. 安装spyder命令: conda install spyder
3. 命令行启动:spyder
当然,开始菜单也可以启动 ---> Spyder (python37)
经过上述步骤后,若想使用python 2.7,则启动“Spyder (Anaconda2)” ;若想使用python 3.x,则启动“Spyder (python37)” 即可,完美!
备注:
安装第三方包:
方法1: conda install xlwt (以安装xlwt 为例)
方法2:采用Anaconda Navigator来安装(开始菜单---启动),简单方便
注意:
如果为python 3.7 安装 第三方包(xlwt),则需要先切到 python37,然后再执行安装
