Python and Django Book Questions

Hello, I'm a sergeant who is interested in web development as a whole and wants to enter.

First of all, my goal is to create a social SNS or interior O2O matching service on the web.

HTml5 or css3 is studying through books and shanko to some extent

The server side wants to select Python and Django.

Here's the question.

http://tryhelloworld.co.kr/ Learn basic knowledge of Python and Django here

I'm trying to learn skills that can be used in practice through the book "Python Web Programming: Practical Edition."

I'm curious about the difficulty level of this book.

If you've read a book or if you're familiar with Python and Django, post it.

Please give me a brief comment on how it will be from the standpoint of beginners.
