Fast API Introduction & Setup:

Fast API is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.

It is easy to use, fast to code with, and has less bugs. It is designed to be fast to run, simple to learn, and easy to use.

Key Features of Fast API:

• Fast: Very high performance, on par with NodeJS and Go (thanks to Starlette and Pydantic).
• Fast to Code: Increase the speed to develop features by about 200% to 300%. (and decrease the number of bugs).
• Intuitive: Very easy to use and to understand. Less time reading the docs.
• Great editor support: Completion everywhere. Less time debugging.

Setup Fast API:

To get started with Fast API, follow these simple steps:

1. Install Fast API using pip:

pip install fastapi

2. Install Uvicorn for the ASGI server:

pip install uvicorn

3. Create a new Python file for your Fast API application.
4. Import the necessary libraries:

from fastapi import FastAPI

5. Create an instance of the FastAPI class:

app = FastAPI()

6. Create your API routes using decorators:

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

With these simple steps, you can start building fast and efficient APIs using Fast API.
