openweather 0.11

News on experimental caching:

The version here in the repository is currently ahead of the latest version distributed on PyPy (0.9). It features Caching.

If the cache isn’t explicitly deactivated, the function “get_historic_weather()” stores data fetched from the API in an SQLite database. On subsequent requests, data is fetched directly from the database, if available.

In order to deactivate the cache, use

ow = openweather.OpenWeather(cache=False)

and in order to explicitly set a path for the cache DB file, use

ow = openweather.OpenWeather(cache="path/to/cache.db")

Install

To install the latest release:

pip install openweather

For the latest version from the repository, use:

pip install git+https://github.com/marians/openweather.git

Python module example

import openweather
from datetime import datetime

# create client
ow = openweather.OpenWeather()

# find weather stations near me
stations = ow.find_stations_near(
    7.0,  # longitude
    50.0, # latitude
    100   # kilometer radius
)

# iterate results
for station in stations:
    print station

# get current weather at Cologne/Bonn airport
# (station id = 4885)
print ow.get_weather(4885)

# historic weather
start_date = datetime(2013, 09, 10)
end_date = datetime(2013, 09, 15)

# default: hourly interval
print ow.get_historic_weather(4885, start_date, end_date)

# daily aggregates
print ow.get_historic_weather(4885, start_date, end_date, "day")

Command line client example

Print current weather at station ID 4885:

$ openweather -s 4885

Print historic weather for 2013-10-01 at station ID 4885:

$ openweather -s 4885 -d 20131001

For valid formats of the -d or --date parameter, see daterangestr.

Print historic data in CSV format

$ python openweather.py -s 4885 -d 20131022 --csv

This is particularly usefull if you want to store that data to a file…

$ openweather -s 4885 -d 20131022 --csv > weather.csv

… or want to manipulate and display it (using csvkit):

$ openweather -s 4885 -d 20131027 --csv|csvcut -c 9,26,30,35,43|csvlook
