天气 API 响应中的 KeyError

Question

我正在制作一个 python 程序，它告诉天气，但遇到以下错误

请告诉如何纠正？

代码

import requests
import json

api = "<MY_API_KEY>"
BASE_URL = "https://api.openweathermap.org/data/2.5/weather?"
print("for which city?")
CITY = input("city?: ")
URL = BASE_URL + "q=" + CITY + "&appid=" + api

response = requests.get(URL)
if __name__ == "__main__":
    data = response.json()
    main = data['main']
    temperature = main['temp']
    humidity = main['humidity']
    pressure = main['pressure']
    report = data['weather']
    print(f"{CITY:-^30}")
    print(f"Temperature: {temperature}")
    print(f"Humidity: {humidity}")
    print(f"Pressure: {pressure}")
    print(f"Weather Report: {report[0]['description']}")

终端

您的代码非常好，我看到的唯一问题是当您输入任何垃圾值时。您需要进行错误处理。
