Coz the re function takes a single RE as a string.
You are trying to take the bitwise OR of two strings
and pass the result. Bitwise ORs don't work with
strings... You need to form the whole RE as a single string.
depending onm exactly what you want.
BTW. Somebody has put on the web a really nice RE syntax
checker written in Python and Tkinter. You might want to
do a search and see if you can pick it up...
> >>> pat = re.compile(('_.*') | ('\..*'))
I suspect this is the correct one if you just wrap it all
as a string...
