python爬取天气可视化代码

您好，以下是爬取天气数据并进行可视化的Python代码：

import requests
import json
import pandas as pd
import matplotlib.pyplot as plt

# 获取天气数据
def get_weather(city):
    url = f'https://free-api.heweather.net/s6/weather/forecast?location={city}&key=yourkey'
    r = requests.get(url)
    data = json.loads(r.text)
    weather_data_list = data['HeWeather6'][0]['daily_forecast']
    return weather_data_list

# 可视化天气数据
def visualize_weather(city, weather_data_list):
    dates = [data['date'] for data in weather_data_list]
    temps_max = [int(data['tmp_max']) for data in weather_data_list]
    temps_min = [int(data['tmp_min']) for data in weather_data_list]

    df = pd.DataFrame({'temps_max': temps_max, 'temps_min': temps_min}, index=dates)
    ax = df.plot(kind='bar', color=['r', 'b'], rot=0)

    ax.set_title(f'{city}天气预报')
    ax.set_xlabel('日期')
    ax.set_ylabel('温度(℃)')

    plt.show()

if __name__ == '__main__':
    city = '北京'
    weather_data_list = get_weather(city)
    visualize_weather(city, weather_data_list)

需要替换代码中的`yourkey`为自己的和风天气apikey。
