[Python] Check-in for the first day of learning - various uses of regular expressions


Event address: CSDN 21-day learning challenge

The biggest reason for learning is to get rid of mediocrity. One day early will bring more excitement to life; one day late will bring more troubles of mediocrity. Dear friends, if you:
Want to systematically/in-depth study a certain technical knowledge point...
It is difficult to persist in learning alone, and you want to form a group to learn efficiently... You
want to write a blog but have no idea how to start, and you are in urgent need of writing dry information to inject energy...
Love writing, and are willing to let yourself become Better people...

Welcome
to participate in the CSDN Learning Challenge and become a better self. Please refer to the free high-quality column resources of high-quality column bloggers in the event (this part of high-quality resources is free and open for a limited time during the event~), according to your own Study the learning areas and learning progress and record your own learning process.

1. Opportunity

Share with everyone the original intention of becoming a creator

  1. Record problems encountered
  2. Share solutions and ideas
  3. Participate in the forum environment

2. Harvest

What are the gains during the creative process?

  1. By publishing more and more solutions to problems, we find that we are becoming more and more efficient in solving problems.
  2. I gained a sense of personal honor from the forum, which made me love this job more and more.

3. Daily

What is the relationship between your current creation and your work and study:

  1. Creation is already part of your life
  2. With limited energy, creation is a supplement to work and study, filling the gap of forgetting caused by memory loss.
