Luftdruck Hessen
================
This tool scrapes the web page of the *Hessian Agency for the Environment and Geology*
offering the air pressure in different cities in an HTML table:
["Aktuelle Luftdruck-Messwerte"][luftdruck].
The Python tool scrapes the site, extracts the values for a given city
and prints the output in JSON, CSV, or Python dictionary format.
Example Usage
-------------
To get the values for "Fürth/Odenwald", run the script like this
python scraper.py --format csv "Fürth/Odenwald"
an you will get this:
# Time, Air Pressure
00:00, 1009.0
00:30, 1009.0
[...]
09:00, 1012.0
09:30, 1011.0
10:00, nan
10:30, 1012.0
11:00, 1012.0
11:30, 1012.0
[...]
22:00, 1016.0
22:30, 1016.0
23:00, 1016.0
23:30, 1016.0
Check [the web page][luftdruck] for other possible city names.
Requirements
------------
To run this script, you need Python (tested with Python 3) and the modules
requests and beautifulsoup4, both of which you can install with `pip`.
Remarks
-------
If the HTML code of the site was better organized, you could parse it with Pandas in Python like this:
import pandas as pd
pressure_url = 'http://www.hlug.de/no_cache/messwerte/luft/meteorologie/luftdruck.html'
dfs = pd.read_html(pressure_url)
