Not sure that's true. Malcolm was indicating that it is a character escape at the reg-exp level, not the Python string-parsing level. Character classes can't be merged in Python reg-exps. \w represents an entire character class, and, consequently, can't be merged with other classes by putting \w inside the new character class. -Forest
