Two scoop of Django
This book contains the best practice for django and python
Programs must be written for people to read, and only incidentally for machines to execute.
Clean Code
I just started to read the Two Scoops Of Django and the first section is all about Clean Code for Django and python. The Python core team and Django core team spend so much effort to make and improving standards like PEP8 and Django Code Style
The book covers essential coding styles and good practice to follow when coding in general and some django specific elements and tips. They also go the extra miles to cover the HTML, CSS and JS coding patterns.
There is a huge load of extra reading to cover that yet to be covered.
