weather underground precipitation history

NCEI Climate Data Online Data Search (search).

DSI 3240_01 contains data grouped by state DSI 3240_02 contains data grouped by year. Accumulation was for longer periods of time if for any reason the rain gauge was out of service or no observer was present. The major parameter in DSI-3240 is precipitation amounts, which are measurements of hourly or daily precipitation accumulation. The latest data in all states and regions is from the present day. Other states and regions have earliest dates between those extremes. The western Pacific region that includes Guam, American Samoa, Marshall Islands, Micronesia, and Palau have data since 1978. The earliest data dates vary considerably by state and region: Maine, Pennsylvania, and Texas have data since 1900. The primary source of data for this file is approximately 5,500 US National Weather Service (NWS), Federal Aviation Administration (FAA), and cooperative observer stations in the United States of America, Puerto Rico, the US Virgin Islands, and various Pacific Islands. Any help would be greatly appreciated.Hourly Precipitation Data (HPD) is digital data set DSI-3240, archived at the National Climatic Data Center (NCDC). I put the URL into a JSON viewer to look at the structure, and cannot figure out what I am doing wrong. When I run this I get an exception 'TypeError: list indices must be integers, not str' The JSON stream includes a bunch of fields with daily summary information (Dailysummary), but I cannot get out and any of the values they have in this list. I adapted their Python example code (see below). I am trying to pull historical data from the Weather Underground API.
