How to use Python and Baidu Map API to obtain city weather forecast information?

Introduction: Weather forecast plays an important guiding role in our daily life. This article will introduce how to use the Python programming language and Baidu Map API to obtain weather forecast information for a city, thereby helping us understand the weather conditions accurately.

First, we need to register a Baidu developer account and create an application. After creating the application, Baidu will provide us with a pair of API Keys for permission authentication using the Baidu Map API.

Next, we will use Python's requests library to send HTTP requests to the Baidu Map API, and use the json library to parse the returned weather forecast data.

The following is a sample code for using Python to obtain city weather forecast:

import requests import json # 替换为你自己的百度地图API Key API_KEY = "Your_API_Key" # 请求的地址和参数 url = "http://api.map.baidu.com/telematics/v3/weather" params = { "location": "北京", "output": "json", "ak": API_KEY } # 发送请求并获取天气数据 response = requests.get(url, params=params) data = json.loads(response.content) # 解析天气数据 weather_data = data["results"][0]["weather_data"] # 打印天气预报 for weather in weather_data: print("日期：", weather["date"]) print("天气：", weather["weather"]) print("风力：", weather["wind"]) print("温度：", weather["temperature"]) print()

In the above code, we first define the API Key and the requested address and parameters. We then use the requests library to send a GET request and get the weather data returned. Next, we use the json library to parse the returned data into a Python dictionary object. Finally, we extract the weather forecast information and print it out.

It should be noted that the sample code here only obtains the weather forecast for Beijing. If you want to get weather forecasts for other cities, just change the value ofparams["location"]to the name of the city you need.

Through the above code example, we can easily use Python to obtain the city's weather forecast information. You can further process the weather forecast data according to actual needs, such as saving the weather forecast information to a file, or performing corresponding operations based on weather conditions.

Summary: This article introduces how to use Python and Baidu Map API to obtain urban weather forecast information. I hope this article can help you obtain city weather forecast information and give you a better understanding of weather conditions to better arrange your daily life. May you always enjoy the good weather!
