Welcome to easierscrape’s documentation!¶
Overview¶
easierscrape is a library which helps users do some basic web scraping operations. Oftentimes when doing webscraping code is written and re-written with slightly changed parameters to fit the website to be scraped from. This library is an easy to use tool that can scrape essentials from websites (tables, links, files, etc.). It also has the ability to generate hyperlink trees using anytree.
Basic Usage¶
Install with pip: pip install easierscrape
Import Scraper
from easierscrape
and instantiate it with a url (and optionally a download_path) as seen below:
from easierscrape import Scraper
scraper = Scraper("https://quotes.toscrape.com/login", "download_dir")
From there, call class methods to scrape varying resources.
Usage examples:
>>> scraper.parse_text()
["Quotes to Scrape", "Quotes to Scrape", "Login", "Username", "Password", "Quotes by:", "GoodReads.com", "Made with", "❤", "by", "Scrapinghub",]
>>> scraper.print_tree(1)
https://quotes.toscrape.com/login
├── https://quotes.toscrape.com
├── https://goodreads.com/quotes
└── https://scrapinghub.com
>>> scraper.print_tree(1, blacklist=["quotes.toscrape.com"])
https://quotes.toscrape.com/login
├── https://goodreads.com/quotes
└── https://scrapinghub.com
>>> scraper.get_screenshot()
True

Downloads¶
Using get_screenshot
, parse_files
, parse_images
, or parse_tables
will result in downloads to the download_path
specified in the Scraper
instantiation. If no path is specified, it will default to downloading to an “easierscrape_downloads” folder.
