How is interaction with the server carried out via the HTTP protocol?

Interacting with a server via the HTTP protocol in Python is usually done using libraries capable of sending HTTP requests and receiving responses.

The most popular way is to use the requests library:

import requests

response = requests.get('https://api.example.com/data')
if response.status_code == 200:
    print(response.text)  # response body
else:
    print(f"Error: {response.status_code}")

Main steps:

1. Form an HTTP request (GET, POST, PUT, DELETE, etc.)
2. Send the request to the server
3. Receive an HTTP response with status code, headers, and body
4. Process the response in the program

Thus, HTTP is a message exchange protocol between client and server, and Python provides tools for convenient work with it.
