lisptick-python

LispTick Python client library

It allows to send request and receive result from a LispTick server.
Get a socket connection to a LispTick server, for example:

• lisptick.org:12006 main server
• uat.lisptick.org:12006 UAT server

Send your request and read the streamed result.

package

lisptick.py is the only module to import.
Add it to your $PYTHONPATH or put it next to your code.

client_test.py is our regression test ensuring each data type is checked.

MeteoNet Example

Here is an example asking for the temperatures on 7th june 2017 2017-07-06 at Poitiers Airport (meteonet code "86027001"), data are coming from MeteoNet.

import lisptick

HOST = "lisptick.org"
PORT = 12006

def main():
    """Ask for temperature at Poitiers airport"""
    conn = lisptick.Socket(HOST, PORT)
    request = """(timeserie @"t" "meteonet" "86027001" 2017-07-06)"""
    timeserie = conn.get_result(request)
    for point in timeserie:
        print(point)

if __name__ == "__main__":
    main()

Examples

Directories with examples for different data sources.
