从开放天气中提取数据 api

Question

我正在尝试从 openweather api 中提取国家天气数据并将其添加到数据框中以便能够创建 csv 文件，但我运行遇到了一些问题。我导入了数据，当我打印它时，我能够以格式化的形式看到请求的数据（湿度、温度、风速等）。我在创建数据框时开始运行遇到问题。

import requests 
import pandas as pd 
import json
from datetime import datetime

API_key = ''

countries = ['Jamaica', 'Haiti', 'Montserrat', 'Barbados', 'Cuba', 'Dominican Republic', 'Saint Lucia', 'Antigua and Barbuda', 'Belize', 'Aruba']

for country_names in countries:
    
    url = f'http://api.openweathermap.org/data/2.5/weather?q={country_names}&APPID={API_key}&units=imperial'
    
    r = requests.get(url)
    
    #if (r.status_code == 200):
        
    data = r.json()
        
    formatted_json = json.dumps(data, sort_keys = True, indent = 4)
        
    
    caribbean_countries = []
    maxtemp = []
    mintemp = []
    humidity = []
    weather = []
    windspeed = []
    
    caribbean_countries.append(data['name'])
    #name = data['name']
    maxtemp.append(data['main']['temp_max'])
    mintemp.append(data['main']['temp_min'])
    humidity.append(data['main']['humidity'])
    weather.append(data['weather'][0]['description'])
    windspeed.append(data['wind']['speed'])
        

countries_weather_df = pd.DataFrame()
countries_weather_df['Names'] = caribbean_countries
countries_weather_df['Max_Temp'] = maxtemp
countries_weather_df['Min_Temp'] = mintemp
countries_weather_df['Humidity'] = humidity
countries_weather_df['Weather'] = weather
countries_weather_df['WindSpeed'] = windspeed

countries_weather_df

结果只显示一个国家。如何显示所有请求的国家并将其放入数据框中？

如何在数据框中显示所有国家/地区？

您需要在 for 循环之前移动 caribbean_countries，否则它会覆盖每次迭代。您还需要为其他值执行此操作，否则它们也会被覆盖。

import requests 
import pandas as pd 
import json
from datetime import datetime

API_key = ''

countries = ['Jamaica', 'Haiti', 'Montserrat', 'Barbados', 'Cuba', 'Dominican Republic', 'Saint Lucia', 'Antigua and Barbuda', 'Belize', 'Aruba']

caribbean_countries = []
maxtemp = []
mintemp = []
humidity = []
weather = []
windspeed = []

for country_names in countries:
    
    url = f'http://api.openweathermap.org/data/2.5/weather?q={country_names}&APPID={API_key}&units=imperial'
    
    r = requests.get(url)
    
    #if (r.status_code == 200):
        
    data = r.json()
        
    formatted_json = json.dumps(data, sort_keys = True, indent = 4)

    caribbean_countries.append(data['name'])
    #name = data['name']
    maxtemp.append(data['main']['temp_max'])
    mintemp.append(data['main']['temp_min'])
    humidity.append(data['main']['humidity'])
    weather.append(data['weather'][0]['description'])
    windspeed.append(data['wind']['speed'])
        

countries_weather_df = pd.DataFrame()
countries_weather_df['Names'] = caribbean_countries
countries_weather_df['Max_Temp'] = maxtemp
countries_weather_df['Min_Temp'] = mintemp
countries_weather_df['Humidity'] = humidity
countries_weather_df['Weather'] = weather
countries_weather_df['WindSpeed'] = windspeed

countries_weather_df
