For example, part of the results from https://check.torproject.org/cgi-bin/TorBulkExitList.py?ip=38.229.72.19&port=443 just now: ``` 37.130.227.133 37.130.227.133 37.131.185.47 37.139.3.171 37.143.9.74 37.147.45.175 37.157.192.208 37.157.194.210 37.157.195.178 37.157.195.83 37.187.107.210 37.187.114.36 37.187.129.166 37.187.129.166 37.187.2.229 37.187.21.180 37.187.239.191 37.187.244.40 37.187.246.221 37.187.38.147 37.187.39.210 37.187.51.210 ``` which has multiple duplicates. I assume the script has a `list.sort()` somewhere in there. All that is needed to get rid of the duplicates is `set(list.sort()`.
