Python API Development – Comprehensive Course for Beginners

What You Will Learn

• Design and build a fully featured API in Python with authentication, current operations, scheme of validation, and documentation
• Learn SQL from the absolute basics, including core concepts like primary keys, foreign keys, and table constraints
• Integrate SQL databases in your API using raw SQL queries and ORMs, and deploy your application on cloud platforms like AWS, GCP, Azure, or Heroku

Key Concepts

• SQL databases: a fundamental component of building robust APIs, allowing for efficient data storage and retrieval
• API development: involves more than just building a simple API, but also setting up documentation, authentication, and validation
• Database migration tools: like alembic, which enable incremental changes to database schema, tracking changes, and version control
• Deployment: the process of making your API available to the public, which can be done on various cloud platforms or using services like Heroku
• Automated testing: a crucial step in ensuring the reliability and stability of your API, which can be achieved using tools like postman and integration tests

Code Examples

• for 19 hours: indicating the comprehensive nature of the course, covering a wide range of topics in API development
• with database migration tools like alembic, which allow us to make incremental changes to our database schema to track changes and get just like we can with our regular Python code: demonstrating the use of alembic for database migration
• if all the tests ultimately pass, it'll actually push out our changes to our production environment, so that we can do all of this in an automated fashion without having to manually go in and run each step manually: illustrating the automation of testing and deployment

Lesson Summary

In this lesson, you learned about the importance of building a fully featured API in Python, including authentication, validation, and documentation. You also gained insight into the role of SQL databases in API development and how to integrate them using raw SQL queries and ORMs. The instructor emphasized the need to cover SQL extensively, starting from the basics, to ensure a solid foundation for building robust APIs. Additionally, you learned about database migration tools like alembic and the importance of automated testing using tools like postman. The lesson also touched on deployment options, including cloud platforms like AWS, GCP, Azure, and Heroku. By the end of this course, you will have acquired the skills to build, test, and deploy your own APIs, making you proficient in API development.

Practice Exercise

Create a simple API in Python that includes basic authentication and validation. Use a SQL database to store user data and implement a simple query to retrieve user information. You can use a library like Flask to build the API and SQLite as your database.

What Is Next

In the next lesson, you will dive deeper into the basics of SQL and learn how to design and implement database schemas for your API. You will also explore the use of ORMs and raw SQL queries to interact with your database, setting the stage for building more complex and robust APIs.
