Yes, you can, however you have two string literals in which you are escaping
the trailing quotation mark. Try this instead:
"*[\s|\w]*" + x +"[\s|\w]*\\" + y + "*[\s|\w]*\\" + y + "*[\s|\w]*"
It's not clear just what you're after, but I think this will probably lead
you further on the path to enlightenment:
r"*[\s|\w]*%(x)s[\s|\w]*\%(y)s*[\s|\w]*\%(y)s*[\s|\w]*" % locals()
where x and y are local variables.
