passing a variable into a regex that would be great.
The same way you pass anything into any string.
Regexes are ordinary strings. If you want to construct a string from a
variable t = "orl", you can do any of these:
"Hello w" + t + "d"
"".join(["Hello", " ", "w", t, "d"])
"Hello w%sd" % t
"Hello %s" % ("w" + t + "d")
"Hello w%(var)sd" % {"var": t}
"Hello wSPAMd".replace("SPAM", t)
or many other variations. Constructing a regex is no different.
You just need to remember that if you pass a string into re.sub as a
replacement then it'll be treated as a template. It's all in the
documentation! :-)
