“bogus escape error” in regex

[rolgiati]

Wanting to remove the parenthesis around the final text between parenthesis at the end of book titles, I tried to replace (.*) \((.*)\)$ with \1 \2 and got the ominous warning:“bogus escape error”

Seem python does not like having the laxt regex character escaped.

But I found a simple bodge to get around the problem.

First step, in Character match, replace ) with )X

Then in Regular expression replace (.*) \((.*)\)X$ with \1 \2

Worked a treat.
