Python day 1, python get the first day of this week

Hello everyone, I can finally use the weekend time to study with everyone. This learning atmosphere reminds me of the time when I went to college.

First, I want to explain why I chose Python.

Currently, I work on Linux system O & M and business technical support. Automated O & M is particularly popular in the past one or two years. I am also very familiar with shell, so I still want to learn a language to help my work. Automated O & M is also a trend. I also believe that the O & M path of system technologies will be narrower and narrower in the future. Python is also called "glue language ".
