Python SDK escaping regular expressions in search

[askjoe]

I am running searches via the Python SDK and having issues when I include regular expressions as part of the search. How do I escape the regular expression so the search can run as expected?

The search regex causing issues:

..... | regex http.hostname="\b(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b" | .......

The error:

ExpatError: not well-formed (invalid token): line 5, column 148

Basically I'm looking to match IP
