I believe I had epiphany:

        test = re.compile('MAT file (billing|carrier|log|util)' r'\\' '\d{8} deleted')

is this correct?

Subject: question regarding regular expression compile

I am determining a regular expression that can recognize the any of the following strings:

MAT file log\20101225 deleted
MAT file billing\20101225 deleted
MAT file util\20101225 deleted
MAT file carrier\20101225 deleted

I begin by creating a regular expression object so that I can reuse it in multiple operations:

        test = re.compile('MAT file

for log, billing, util, and carrier I use an arbitrary match:


for 20101225 I use decimal digit with repetition match:


and finish with:


My question is how do I handle the backslash (NOTE: the match must only be a backslash)?
