Do you see the difference between:
rx_a = re.compile(r'a|b|c')
rx_a = re.compile("r'a|b|c'")
There is no difference in the variable datatype between "string" and "raw
string". Raw strings are just a notational helper when creating string
literals that have lots of backslashes in them (as happens a lot with
r'a|b|c' is the same as 'a|b|c'
r'\d' is the same as '\\d'
There is no reason to "add raw strings" to your makeRE method, since you
don't have a single backslash anywhere. And even if there were a backslash
in the 'w' argument, it is just a string - no need to treat it differently.
