PyOWM 每日天气图标

Question

我研究了 PyOWM 和 OWM API 指南以及一些代码配方，并且在大量代码中可以正常工作，但我就是不知道如何获取今天预报的当前天气图标？这是一个与图标不同的代码 sn-p：

from pyowm.owm import OWM
from pyowm.utils import timestamps
import requests, json

def checkInternetRequests(url='http://www.google.com/', timeout=3):
    try:
        r = requests.head(url, timeout=timeout)
        return True
    except requests.ConnectionError as ex:
        print(ex)
        return False

def get_weather():
  if checkInternetRequests() == True:
    # 52.5766° N, 1.5438° W
    print ("Internet Up")
    CITY = "Atherstone, GB"
    LON = 1.54
    LAT = 52.576 
    API_KEY = "myapikey"
    ICON_URL_1 = "http://openweathermap.org/img/wn/"
    ICON_URL_2 = "@2x.png"
    owm = OWM(API_KEY)
    mgr = owm.weather_manager()
    one_call = mgr.one_call(lat=LAT, lon=LON)

    print (one_call.forecast_hourly[3]) #works - 3hrs from now
    print ("===========================")
    print (one_call.forecast_daily[0]) # works - Today
    print ("===========================")
    print (one_call.forecast_daily[0].weather.icon)

  else:
    print ("Internet Down")
    time.sleep(10)

get_weather()

我收到以下错误：

Traceback (most recent call last):
  File "weather1.py", line 37, in <module>
    get_weather()
  File "weather1.py", line 31, in get_weather
    print (one_call.forecast_daily[0].weather.icon)
AttributeError: 'Weather' object has no attribute 'weather'

我哪里错了？谢谢！

Answer 1

好的 - 喝了几杯啤酒和一些食物，再加上 4 小时的代码弄乱后，我可以正常工作了！

one_call.forecast_daily[0].weather_icon_url()

给了我一个网址，我可以用它在我的代码中显示今天的预测图标。

import pyowm
from pyowm.utils import timestamps, formatting
from pyowm.owm import OWM
import matplotlib.pyplot as plt
import matplotlib.image as mpimg

observation = mgr.weather_at_place('London')
w = observation.weather
icon = w.weather_icon_url(size='2x')

img = mpimg.imread(icon)
plt.imshow(img)
plt.show()
