正在检查与python的Internet连接

Question

这是在python中检查Internet连接的好方法吗？据我所知，我不应该使用纯粹的例外。

import urllib.request
import time

def connect():
try:
urllib.request.urlopen('http://google.com')
return True
except:
return False

while True:
if connect():  # checks if there is Internet connection
print('Connected to Internet.')
else:
print("No Internet.")
time.sleep(10)
continue  # Loops to beginning and checks for Internet connection again
main_function()

Answer 1

试试这个代码：

import socket
ip = socket.gethostbyname(gethostname)
if ip="127.0.0.1":
print("Not Connected")
else:
print("Connected!")
