Recommended books for python 2.7 data structures and algorithms

I am currently using Python (series 2), but I would like to study because I have little understanding of data structure and algorithms.
I understood that there are various summary sites and study sites, but if you know that there are no books in the form you want,
I would appreciate it if you could let me know if you have any recommendations.

Current method of study;
1. Understand the basic data structure and algorithms by looking at the website.
2.Find challenges using them from the competition programming practice site
3. Try writing in Python yourself
4. Find what others are writing and think about the correct answer
→ It takes time to find each and every one of them, so I thought it would be good to have them all in books, but I couldn't find a good one in python.
What you want;
- Describes the contents, differences, and how to use the basic algorithms and data structures.
- There is a problem using it
- Answers are written in python (series 2)
