Following the upgrade f38->f40 I started getting warnings and errors. This is

What is the correct escapes to select strings starting with (AD) and [AD]?
/usr/local/bin/mythtv-fix-descriptions.py:33: SyntaxWarning: invalid escape
sequence '\['
re_tag = re.compile ("^[\[(]AD[\])] *")
If I remove the escapes I get:
/usr/local/bin/mythtv-fix-descriptions.py:33: FutureWarning: Possible nested
set at position 2
re_tag = re.compile ("^[[(]AD[])] *")
However making it a raw string removes the warning, but will it do the right
thing?
re_tag = re.compile (r"^[\[(]AD[\])] *")
Assuming myth follows the basic RE syntax, square brackets must be included in
a class positionally, not by escaping them. They must
immediately follow the opening square bracket. This should do it.
^[[(]AD[])]
Note however two undesired strings will match
[AD) and (AD]
True, but these do not occur in the data.
