Question

我正在使用pyowm每分钟后获取天气更新。如果我断开互联网连接或互联网连接中断，将会发生什么错误以及如何处理此错误。对于try..except方法，。必须使用什么可能的例外...？我的代码是...。

import tkinter as tk
from tkinter import *
import pyowm
from PIL import ImageTk, Image


win=tk.Tk()



#frame_for_showing_weather.
weather_frame=Frame(win,bg='black',width='300',height='300')
weather_frame.place(x=0,y=0)

weath=Label(weather_frame,font=('Agency',100),fg='white',bg='black')
weath.place(x=10,y=10)

temp1=''
owm=pyowm.OWM('my api key')

def obs():
    global temp1
    observation = owm.weather_at_place('Barisal,BD')
    w=observation.get_weather()
    temp2=w.get_temperature('celsius')
    if(temp2!=temp1):
        temp1=temp2['temp']
        weath.config(text=str(int(temp1))+chr(176))
        print('Alhamdulillah,Yeah that is worked')
    weath.after(60000,obs)
obs()


win.mainloop()

请有人解释...我是python的新手。

如果我断开连接，则会发生此大错误...
