[Tutor] use of variables in re.sub

[Eva Bofias]

Helo,

I need to do a substitution in a regular expression that depends on a
variable. To simplify I want to be able to do this substitution:

text2='XX. AA YY. DD'
re.sub(ur"\. (AA|BB|ÇÇ","(.) \g<1>",text2)

this would give as a result:
'XX(.) AA YY. DD'
Which is exactly what I want.

But when I try to substitute AA|BB|CC for a variable I do not know how to
make it work.
I wanted to use re.compile. I tryed:

NP= u"AA|BB|ÇÇ"
reNP=re.compile(ur'%s'%NP)

But if I try:

reNP.match(text2)

And I do not know how to use the variables in there. Should I use
re.compile or is there something else that I should be using

Thank you
