Creating API’s in Python using FastAPI

FastAPI is a modern web framework for building APIs with Python. It is fast, easy to use, and highly customizable. In this tutorial, we will learn how to create API’s using FastAPI.

Step 1: Installation

To get started, you need to install FastAPI. You can do this using pip:

pip install fastapi

Step 2: Create a Python file

Create a new Python file and import FastAPI:

from fastapi import FastAPI

Step 3: Create an instance of FastAPI

Create an instance of FastAPI and define your API endpoints:


app = FastAPI()

@app.get('/')
def read_root():
return {"message": "Hello World"}


Step 4: Run the server

Run the server using uvicorn:

uvicorn your_file_name:app --reload

Now you can test your API by visiting the URL provided by uvicorn in your browser.

Step 5: Add more endpoints

You can add more endpoints to your API by creating more functions and decorating them with the appropriate HTTP method decorator, such as @app.post or @app.put.

Conclusion

Creating API’s in Python using FastAPI is easy and efficient. With its automatic interactive documentation and type checking features, FastAPI makes building API’s a breeze. Try it out for yourself and start building powerful APIs with Python!
