Hello, I don't know much about programming. Do not swear too much, explain how various kinds of parsers for social networks are written? What do you need to study for this, where to read? I'll listen to whatever you say :-)

Answer 1

If you want to parse info from vk, then python has a special module for working with vk api, by studying the syntax and reading the documentation along the way, you can write some simple parser to start with.

Answer 2

Firstly, there are pages "for developers", which describe the API for working with a social network through, for example, GET requests.
Secondly, there are frameworks for html parsing in the public domain.

Answer 3

explain how they write various kinds of parsers for social networks?

Usually parsers for social. networks are not written, since social. networks provide fairly broad APIs. If you look more generally: "different kinds of parsers" are written in different ways, it's like asking "how are different kinds of food cooked?".
Knowledge of web principles, HTML+CSS and at least one programming language capable of working with the web.
Then it’s better not to bother and contact any freelance exchange. It's just that for your goal "you need a parser for a social network, but I don't know anything" it will take at least half a year, this is with the most successful scenarios.
