weather data extraction using Pandas and visualization using Plotly

[Sebastian M Cheung]

How to extract weather from this api and use Plotly to visualize weather data:

I understand this would get historical data for past 15 days..

http://api.openweathermap.org/data/2.5/history/city?q=Paris,FR&type=hour&start=1369728000&end=1369789200

Thanks

Specifically I want to extract say from Paris, FR the latitude and longitude:

2.34880, 48.853409

which is embedded as id 2988507 Paris 2.34880 58.853409, at the moment it is hardcored and provided

(lon, lat) = (2.34880, 48.853409)  # Paris

Your data appears to be in JSON format. In terms of how to work with it, I would look at the python documentation for parsing JSON: https://docs.python.org/3.4/library/json.html

Alternatively if you intend to do more complicated analysis, pandas read_json may be helpful: http://pandas.pydata.org/pandas-docs/stable/io.html#io-json-reader

If you search for 'openweathermap python', you can find some different projects providing a python interface to download the data. That could maybe also help.
