Checking for IP addresses

Question

Are there any existing libraries to parse a string as an ipv4 or ipv6 address, or at least identify whether a string is an IP address (of either sort)?

Answer 1

If you know for sure that the address is valid and only trying to decide whether it is ipv4 or ipv6, wouldn't it be sufficient to do just:

if ":" in address:
    print("Ipv6")
else:
    print("Ipv4")
