import requests, pytemperature, json

r = requests.get('http://samples.openweathermap.org/data/2.5/forecast?
lat=35&lon=139&appid=b1b15e88fa797225412429c1c50c122a1')
dict = r.json()

for key, value in dict.items():
    if 'dt_txt' in str(key):
        print(key)

旁注:最后,我试图打印日期、temp\u min、temp\u max、main和描述。我将把温度从开尔文转换成华氏度,然后用gmail每天发短信给我新的预测。提前感谢您的帮助!

您可以通过您的dict['your\u value']来设置所有dict键,请尝试以下操作:

import requests, json

r = requests.get('http://samples.openweathermap.org/data/2.5/forecast?lat=35&lon=139&appid=b1b15e88fa797225412429c1c50c122a1')
dict = r.json()
select_data = dict['list']

for box in select_data:

    if 'dt_txt' in box:
        print(box['dt_txt'])

    else:
        print('not found')
