I'm developing a Python application to check the external IP and save to a database, the problem is the following function:

def pega_ip(): ip = get('https://api.ipify.org').text return ip

Because it uses the get method to receive content directly into a variable, when there is no internet connection, the error occurs:

File "/usr/local/lib/python3.5/dist-packages/requests/adapters.py", line 508, in send raise ConnectionError (e, request = request) requests.exceptions.ConnectionError: HTTPSConnectionPool (host = 'api.ipify.org', port = 443): Max retries exceeded with url: / (Caused by NewConnectionError (': Failed to establish a new connection: [Errno -3] Temporary failure in name resolution ',))

I need to handle this problem because the program is terminated when this error occurs, I need that if the connection crashes it will continue executing and trying to access this url in order to get the external IP.

You only have to put in while and catch the exception when it occurs:

def pega_ip(): 
    while True:
        try:
            ip = get('https://api.ipify.org').text
            return ip
        except ConnectionError:
            pass

So, if there is an exception, it will immediately try again. If it does not, it arrives at return and the function exits.
