Extract juggling trick data (name, difficulty, prerequisites) from http://libraryofjuggling.com/ with python and scrapy.
The scraped data is written to a csv file, every row representing a trick in the format:
<Name>,<NumBalls>,<Difficulty>,<Prerequisites-list>
NelsonsNemesis,5,Columns,RubensteinsRevenge
A trick may also have several prerequisites which are recommended to train before learning this one. If a trick is a variation of some trick, such as 'Reverse Chops' is a variation of 'Chops', we add the prefix [<Parent_Name>] to a trick name. But only in the first column. Prerequisites are not named with the parent prefix.
You can find the data in 'juggling_tricks.csv'
This code was written in order to use the extracted data for another project.
Install: pip install scrapy
Run with 'scrapy crawl loj'
