Abstract

As the ever increasing data in the today’s world data can be used in various ways. Thus web scraping helps you obtain that data efficiently and also saves a ton of time by making the data collection an automated task.

So the talk will be focused on getting started in web scraping using python. Scraping in python can be done in various different ways, the aim of this talk to provide the attendees with nitty-gritty details so that at the end of the talk, attendees will be able to judge on their own what approach to take and what libraries/tools to use depending on the problems they intend to solve. The talk will cover useful scraping libraries/tools and neat tricks and techniques required to scrape even the hard-to-scrape sites effectively. Hard-to-scrape can be described as sites which load the DOM with Javascript, or need authentication, or require captchas , involving cookies, e. t.c.

Also the talk will go through some real world example codes to give the attendees a gist of what all it takes to successfully extract the data they require. At the end some scraping ethics will be mentioned so that one doesn’t end up putting anyone in trouble.
