Description

We will learn to:
– work with requests
– extract the necessary data from the page
– consider GET, POST requests
– consider headers, data arguments
– learn how to create a session to save cookies
– learn to simulate user actions
– learn how to log in to sites, download and send files
– study the architecture client/server
– we will look at the principle of thehttp protocol
– we will learn how to parse all the pages of the site
– we will learn how to find the values we need on the website
– we will look at multiprocessor programs, to speed up the work of the software
– we will learn to replace the user-agent and simulate another device and browser
– we will consider all the basics bs4

Will we do it?
– write a program to extract the user’s IP
– write a program to download files from the site
– learn to bypass all the pages of the site and replace the user-agent
– write a program using multiprocessing
– write a program using bs4

Why this particular course?
– the material is aimed at any level of knowledge of Python (suitable for a beginner and p professional)

– the course does not contain water and provides only the necessary information
– after this course you will be able to fully work with the studied libraries
– simple presentation of the material
– contains real examples and tasks
– relevant information
– we consider all the listed libraries in one course at a minimal cost

After completing this course you will be able to develop parsers, creators, various bots to automate actions in the browser and simulate all actions that a person can perform using a browser and certain sites. Services of parsing and automation of web resources are very often found on freelance, so you can recoup this knowledge almost immediately after passing the course.
Who this course is for:

Beginner Python developers who want to learn how to use site scraping in their work
Python developers who want to learn how to parse data
