Pyowm api中的异常问题

Question

我正在编写Python上非常原始的脚本，它在控制台中提供当前的wheather信息。所以一切正常，但是如果我输入了错误的城市名称（例如，Nev Uork），控制台中会出现一个异常。在

API-pyowm

Traceback (most recent call last):
File "C:\Users\Dismay\Documents\Python\WeatherHelper2.py", line 28, in <module>
main = owm.weather_at_place(place)
File "C:\Users\Dismay\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pyowm\webapi25\owm25.py", line 210, in weather_at_place
_, json_data = self._wapi.cacheable_get_json(uri, params=params)
File "C:\Users\Dismay\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pyowm\commons\http_client.py", line 44, in cacheable_get_json

raise api_response_error.NotFoundError('Unable to find the resource')
pyowm.exceptions.api_response_error.NotFoundError: The searched item was not found.
Reason: Unable to find the resource

我想捕捉这个异常并打印类似的内容：

^{pr2}$

我试了很多次，但总是失败。你知道如何正确处理api的异常吗？

谢谢大家的关注！ 下面是完整的代码。在

import pyowm
import time 
from colorama import * 
from pyowm.exceptions import *

init(autoreset = True)

print(Fore.BLACK + Back.WHITE + 'Let`s go')



owm = pyowm.OWM('bbc3649126d17d7bb4111c44c6a562d5')
place = input("Place you find: ")

main = owm.weather_at_place(place)
weather = main.get_weather()
maxtemp = weather.get_temperature("celsius")["temp_max"] 
midtemp =  weather.get_temperature("celsius")["temp"]
mintemp = weather.get_temperature("celsius")["temp_min"]
speedwind = weather.get_wind()["speed"]
status = weather.get_detailed_status()
azimuth = weather.get_wind()["deg"]
humidity = weather.get_humidity()

try:
    owm.weather_at_place(place)
except (urllib3.exceptions.ReadTimeoutError, 
api_response_error.NotFoundError('Unable to find the resource')):
print("""Wrong information, try again
and find out mistakes please""")
    time.sleep(10)

此外，只在屏幕上显示功能的内容

我刚刚宣布了try-catch循环中的变量“main”，代码现在正在工作。谢谢大家的关注和帮助！在

Answer 2

你说“总是失败”是什么意思？你犯了什么样的错误/不当行为？在

顺便说一句，你的异常捕捉代码是错误的（因为它实际上实例化了一个异常！）。试试这个：

import pyowm
from pyowm.exceptions import api_response_error
try:
    owm.weather_at_place(place)
except api_response_error.NotFoundError:
    print('Wrong information, try again and find out mistakes please')
    time.sleep(10)
