As detailed at [1],

(One or more letters from the set 'i', 'L', 'm', 's', 'u', 'x'.) 
The group matches the empty string; the letters set the 
corresponding flags: re.I (ignore case), re.L (locale dependent), 
re.M (multi-line), re.S (dot matches all), re.U (Unicode 
dependent), and re.X (verbose), for the entire regular 
expression. (The flags are described in Module Contents.) This is 
useful if you wish to include the flags as part of the regular 
expression, instead of passing a flag argument to the compile() 
function.
"""

So you should be able to insert "(?m)" at the beginning of your 
regexp to make it multiline.
