问题 Objective: Write Python 2.7 code to extract IPv4 addresses from string. String content example: The following are IP addresses: 192.168.1.1, 8.8.8.8, 101.099.098.000. These can also appear as 192.168.1[.]1 or 192.168.1(.)1 or 192.168.1[dot]1 or 192.168.1(dot)1 or 192 .168 .1 .1 or 192. 168. 1. 1. and these censorship methods could apply to any of the dots (Ex: 192[.]168[.]1[.]1). As you can see from the above, I am struggling to find a way to parse through a txt file that may contain IPs
