示例
以geojson格式获取某个点的预测：
>>> import nwswx
>>> nws = nwswx.WxAPI('your@email.com')
>>> forecast = nws.point_forecast(39.0693, -94.6716)
>>> print(forecast)
{
"@context": [
"https://raw.githubusercontent.com/geojson/geojson-ld/master/contexts/geojson-base.jsonld",
{
"wx": "https://api.weather.gov/ontology#",
"geo": "http://www.opengis.net/ont/geosparql#",
"unit": "http://codes.wmo.int/common/unit/",
"@vocab": "https://api.weather.gov/ontology#"
}
], ...
获取JSON-LD格式的点预测：
>>> import nwswx
>>> nws = nwswx.WxAPI('your@email.com')
>>> forecast = nws.point_forecast(39.0693, -94.6716, return_format=nwswx.formats.JSONLD)
>>> print(forecast['periods'])
[{'number': 1, 'name': 'Tonight', 'startTime': '2019-01-13T22:00:00-08:00', 'endTime':

以json-ld格式获取点的每小时预测：
>>> import nwswx
>>> nws = nwswx.WxAPI('your@email.com')
>>> forecast = nws.point_hourly_forecast(39.0693, -94.6716, return_format=nwswx.formats.JSONLD)
>>> print(forecast['periods'])
[{'number': 1, 'name': '', 'startTime': '2019-01-16T19:00:00-08:00', 'endTime':
'2019-01-16T20:00:00-08:00', 'isDaytime': False, 'temperature': 42,

'NE', 'icon': 'https://api.weather.gov/icons/land/night/rain,90?size=small',
'shortForecast': 'Light Rain', 'detailedForecast': ''}, ...
获取Atom格式的点的活动天气警报：
>>> import nwswx
>>> nws = nwswx.WxAPI('your@email.com')
>>> alerts = nws.active_alerts({'point': '39.0693,-94.6716'}, return_format=nwswx.formats.ATOM)
>>> print(alerts)
