To get the most out of this book

This book requires some experience with Python programming using Python 3.8 or 3.9, as well as some API development experience with any Python framework. Knowledge of the standards and best practices of coding Python, including some advanced topics such as creating decorators, generators, database connectivity, request-response transactions, HTTP status codes, and API endpoints, is required.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.

Each chapter has a dedicated project prototype that will describe and explain the topics. If you get lost during setup, each project has a backed-up database (.sql or .zip) and a list of modules (requirements.txt) to fix some issues. Run the \i PostgreSQL command to install the script file or use the mongorestore from the installed Mongo Database Tools to load all the database content. Also, each project has a mini-readme that gives a general description of what the prototype wants to accomplish.
