问题
I have regular expression like
match = re.findall(r'[0-9]+(?:\.[0-9]+){3}', source)
It works fine to take something like 192.168.1.1 from source string. How I can modify this regular expression for make it work with something like this:
192.168.1.1:80
Thank You for help.
P.S. Sorry for my bad english.

This will match IP addresses with ports numbers.
match = re.findall(r'[0-9]+(?:\.[0-9]+){3}:[0-9]+', source)
If you want to make it flexible to match IP address without the ports and With the ports, you can use:
match = re.findall(r'[0-9]+(?:\.[0-9]+){3}(:[0-9]+)?', source)
