Your task: write a script to get a nice CSV file of natural gas prices.
Please publish your results in a git repo or a gist. Please include both script and your resulting data -- so the CSV files should be stored in the repo too!
More detail:
- Prices should be Henry Hub gas prices. Use EIA data here: http://www.eia.gov/dnav/ng/hist/rngwhhdm.htm
- Hint: you can get the data from any data source on the page ...
- Main data wanted is daily prices.
- Bonus points for doing other granularities (e.g. month) - do them in separate CSV files with sensible naming
- Resulting CSV should have two columns: Date and Price. You may need to normalize the data to get this and/or work out dates. For months the Date should be the first date of the month.
- We want a script for this and we want this script to be in python (we'd allow node or bash or go script at a push but prefer python)
- Why a script? Ans: We'll want to run this again and again as they release new data. You could copy and paste data into Excel/Google Docs by hand, and then export the CSV. But that would be tedious, time consuming and error prone to do month after month
- Please use simple python libraries wherever possible rather than use a framework
Bonus items (optional - extra kudos if you do either of these!):
- Make your repository into a Tabular Data Package - here's a guide
- Do a line graph visualization of the data in HTML + Javascript using e.g. vega or direct in D3
- Deploy your repo somewhere so this visualization is visitable online e.g. via github or gitlab pages
