当您请求2天以上的天气预报时如何对开放式天气地图API响应进行排序

Question

大家好，这是我的第一篇文章。我为此付出了很多努力。当您要求多天预报时，阵列确实令人头疼它看起来像这样：

我有一个星期努力将每天的预测分开。然后在我的程序上打印一些基本值，例如温度和湿度。另外，我正在使用tkinter构建一个GUI以显示每天的天气预报。'

如果您想查看程序代码：https://github.com/zafalex88/open_weather_project/

欢迎大家提出意见。

谢谢你！亚历克斯

Answer 1

您可以打印

print( data['list'][0]['humidity'] )
print( data['list'][1]['humidity'] )

或使用循环

for day in data['list']:
    print('humidity:', day['humidity'])

最小工作示例-它还使用datetime将dt（时间戳）转换为日期

import datetime

data = {"city":{"id":261779,"name":"Ioannina","coord":{"lon":20.8508,"lat":39.6675},"country":"GR","population":64012,"timezone":7200},"cod":"200","message":1.6748099,"cnt":3,"list":[{"dt":1581674400,"sunrise":1581658280,"sunset":1581696629,"temp":{"day":5.85,"min":5.34,"max":6.89,"night":6.73,"eve":6.19,"morn":5.34},"feels_like":{"day":3.07,"night":5.55,"eve":3.59,"morn":3.04},"pressure":1019,"humidity":97,"weather":[{"id":502,"main":"Rain","description":"heavy intensity rain","icon":"10d"}],"speed":2.49,"deg":197,"clouds":100,"rain":38.63},{"dt":1581760800,"sunrise":1581744606,"sunset":1581783100,"temp":{"day":8.65,"min":3.92,"max":10.93,"night":3.92,"eve":9.52,"morn":5.04},"feels_like":{"day":5.27,"night":0.66,"eve":6.49,"morn":1.8},"pressure":1020,"humidity":67,"weather":[{"id":800,"main":"Clear","description":"sky is clear","icon":"01d"}],"speed":2.65,"deg":31,"clouds":4},{"dt":1581847200,"sunrise":1581830931,"sunset":1581869570,"temp":{"day":9.25,"min":2.54,"max":11.97,"night":3.2,"eve":10.1,"morn":2.62},"feels_like":{"day":7.09,"night":0.06,"eve":8.26,"morn":-0.71},"pressure":1028,"humidity":57,"weather":[{"id":802,"main":"Clouds","description":"scattered clouds","icon":"03d"}],"speed":0.5,"deg":59,"clouds":31}]}

for day in data['list']:

    date = datetime.datetime.fromtimestamp(day['dt'])
    print('date:', date)

    print('humidity:', day['humidity'])

    #print('temp:', day['temp'])
    print('temp day:', day['temp']['day'])
    print('temp min:', day['temp']['min'])
    print('temp max:', day['temp']['max'])

结果：

date: 2020-02-14 11:00:00
humidity: 97
temp day: 5.85
temp min: 5.34
temp max: 6.89
date: 2020-02-15 11:00:00
humidity: 67
temp day: 8.65
temp min: 3.92
temp max: 10.93
date: 2020-02-16 11:00:00
humidity: 57
temp day: 9.25
temp min: 2.54
temp max: 11.97

带有tkinter的最小示例

import tkinter as tk
import datetime

data = {"city":{"id":261779,"name":"Ioannina","coord":{"lon":20.8508,"lat":39.6675},"country":"GR","population":64012,"timezone":7200},"cod":"200","message":1.6748099,"cnt":3,"list":[{"dt":1581674400,"sunrise":1581658280,"sunset":1581696629,"temp":{"day":5.85,"min":5.34,"max":6.89,"night":6.73,"eve":6.19,"morn":5.34},"feels_like":{"day":3.07,"night":5.55,"eve":3.59,"morn":3.04},"pressure":1019,"humidity":97,"weather":[{"id":502,"main":"Rain","description":"heavy intensity rain","icon":"10d"}],"speed":2.49,"deg":197,"clouds":100,"rain":38.63},{"dt":1581760800,"sunrise":1581744606,"sunset":1581783100,"temp":{"day":8.65,"min":3.92,"max":10.93,"night":3.92,"eve":9.52,"morn":5.04},"feels_like":{"day":5.27,"night":0.66,"eve":6.49,"morn":1.8},"pressure":1020,"humidity":67,"weather":[{"id":800,"main":"Clear","description":"sky is clear","icon":"01d"}],"speed":2.65,"deg":31,"clouds":4},{"dt":1581847200,"sunrise":1581830931,"sunset":1581869570,"temp":{"day":9.25,"min":2.54,"max":11.97,"night":3.2,"eve":10.1,"morn":2.62},"feels_like":{"day":7.09,"night":0.06,"eve":8.26,"morn":-0.71},"pressure":1028,"humidity":57,"weather":[{"id":802,"main":"Clouds","description":"scattered clouds","icon":"03d"}],"speed":0.5,"deg":59,"clouds":31}]}

root = tk.Tk()

tk.Label(root, text='humidity').pack()

listbox = tk.Listbox(root)
listbox.pack()

for day in data['list']:
    #listbox.insert('end', day['humidity'])
    date = datetime.datetime.fromtimestamp(day['dt'])
    text = '{}: {}'.format(date.strftime('%Y.%m.%d'), day['humidity'])
    listbox.insert('end', text)


root.mainloop()
