How do I target an error as result of timeout in python

Question

I am writing a function to restart my code whenever there is a connection problem.

whenever I disconnect my WiFi, the following is generated.

File "C:\Users\m2jto\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\connection.py", line 174, in _new_conn conn = connection.create_connection( File "C:\Users\m2jto\AppData\Local\Programs\Python\Python310\lib\site-packages\urllib3\util\connection.py", line 72, in create_connection for res in socket.getaddrinfo(host, port, family, socket.SOCK_STREAM): File "C:\Users\m2jto\AppData\Local\Programs\Python\Python310\lib\socket.py", line 955, in getaddrinfo for res in _socket.getaddrinfo(host, port, family, type, proto, flags): socket.gaierror: [Errno 11001] getaddrinfo failed

How do I target this error so I can use except block to restart my code?

  except:
      restart()

Answer 1

If you're trying to catch a specific exception, you can specify it in except:

except socket.gaierror:
    restart()

Answer 2

You can catch a generic exception with:

except Exception as e:
     print(f"Exception has been raised: {e}")
     restart()
