FAST API

Question 1

Can you teach me about fast api? I don’t understand it at all!

Answer 1

Certainly! FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints. It is built on top of Starlette for the web parts, and uses Pydantic for the data parts.

Question 2

Key Features?

Answer 2

Here are some of the key features of FastAPI:

Fast: FastAPI is one of the fastest Python web frameworks. It has been benchmarked as one of the fastest web frameworks available.
Easy: FastAPI is easy to learn and use. It is based on standard Python type hints, which makes it easy to understand and learn.
Automatic documentation: FastAPI automatically generates documentation for your API using the OpenAPI specification. The documentation is available at a URL that is predictable and easy to remember.
Automatic validation: FastAPI automatically validates request and response data using the Python type hinting system. This helps ensure that your API is working as intended and reduces the amount of error-checking code you need to write.
Here’s an example of a simple “Hello, World!” application using FastAPI:

Question 3

Here’s an example of a simple “Hello, World!” application using FastAPI:

Answer 3

from fastapi import FastAPI

app = FastAPI()

@app.get(“/”)
async def read_root():
return {“Hello”: “World”}

Question 4

What is an API?

Answer 4

An API (Application Programming Interface) is a set of rules that specifies how two software programs should interact with each other. It defines the kinds of calls or requests that can be made, how to make them, the data formats that should be used, the conventions to follow, etc.

APIs allow different software systems to communicate with each other and share data and functionality. For example, a website that displays weather information might use an API to retrieve data from a weather forecasting service. An API specifies the way that the website can request data from the service, as well as the format that the service will use to return the data.

APIs can be created for a variety of purposes. Some examples include:

Allowing third-party developers to access and use the functionality of a software system
Enabling different components of a software system to communicate with each other
Exposing data from a database or other storage system to be used by other software systems
Providing a way for different software systems to trigger actions in each other
I hope this helps give you a better understanding of APIs! Let me know if you have any questions.
