Request

If we are a little familiar with the English language, we can guess what we are about to discuss.

Imagine a classroom scenario.

Teacher: "Last week we discussed Back-End Engineering. Now we will discuss Cloud."

You were absent for the whole week, so you ask the teacher:

You: "I was absent for the whole week. Can you explain these topics to me?"

This is a normal daily-life request. You are asking the teacher for something.

The teacher may respond:

Teacher: "Okay, I'll explain it."

or

Teacher: "Ask your friend; I don't have time right now."

This is the response to your request.

The same basic idea exists in web communication. When a client makes a request to a server, the server processes that request and sends back a response.

Request → Server → Response

In Python, we can use libraries such as requests or httpx to make HTTP requests.

For example:
import requests

URL = "www.techsnap.in
response = requests.get(URL)
When a user performs an action, the client (such as a browser or mobile application) sends an HTTP request to the server, usually using a URL, HTTP method, and other request information. The server processes the request and sends back an HTTP response.
