python3 pip Pandas

mac自带的python版本2.7。建议安装python3

WARNING: Python 2.7 is not recommended. 
This version is included in macOS for compatibility with legacy software. 
Future versions of macOS will not include Python 2.7. 
Instead, it is recommended that you transition to using 'python3' from within Terminal.

　　

我下载安装了Python 3.9.5

安装 pandas需要使用 pip 。python3是默认安装了pip。对应版本pip 21.1.1

安装pandas最后还是豆瓣的镜像好用
