I am curious as to how python is connected to websites [closed]

Question

I am a new programmer and I saw that Google is written in python. I know that HTML, CSS, and JS are used to make websites, so how is python "linked" to this. This is probably a very basic question but I am new to all this.

Answer 1

So your code in browser is called front-end (FE). Sometimes it's all you need. However, sometimes you need to store some data on the server and/or retrieve it from there. That is where back-end (BE) comes into play.

BE is basically an app on some computer (maybe a server, maybe a Raspberry Pi, anything really) that listens to requests from the network. Let's say your code needs some data from the server. Your code on the front end makes an AJAX request to the network address of this server on some specific port. The BE, which may be written in Python, or any other language, receives the request and does something with it.

It can fetch data from the DB or anything really. Then it send a response to your FE back, sending some data, or confirmation that everything was done successfully, or an error if something went wrong.

Answer 2

Python is used for backend development. Backend is the part of your website that runs on your server, not browser. Backend is used for authentication and communicating with database and many more. There are some popular frameworks in python like django and flask.
