Python API Development Fundamentals

By: Jack Chan, Ray Chung, Jack Huang

Overview of this book

Python is a flexible language that can be used for much more than just script development. By knowing the Python RESTful APIs work, you can build a powerful backend for web applications and mobile applications using Python. You'll take your first steps by building a simple API and learning how the frontend web interface can communicate with the backend. You'll also learn how to serialize and deserialize objects using the marshmallow library. Then, you'll learn how to authenticate and authorize users using Flask-JWT. You'll also learn how to enhance your APIs by adding useful features, such as email, image upload, searching, and pagination. You'll wrap up the whole book by deploying your APIs to the cloud. By the end of this book, you'll have the confidence and skill to leverage the power of RESTful APIs and Python to build efficient web applications.

SQL

SQL is a language that was specifically invented to manage and maneuver data. It can be classified further into the following types:

  • Data Query Language (DQL) for extracting data. With the syntax like SELECT column1, column2 FROM table WHERE conditions, it can query against the table and extracts data (column1, column2) that satisfies a certain condition.
  • Data Manipulation Language (DML) for manipulating data. It includes statements such as INSERT, UPDATE, and DELETE.
  • Data Control Language (DCL) for controlling data access.

Although we have introduced a number of different languages here, the good thing is that we don't need to learn all of them. In fact, we are not going to query our database using SQL. We will just need to code in Python, and the ORM package will convert our Python code to SQL behind the scenes. It's a whole lot easier to work with databases nowadays.
