why not just compile a bad expression and
see what happens? ;-)

>>> re.compile("(")
Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "C:\py152\lib\re.py", line 79, in compile
    code=pcre_compile(pattern, flags, groupindex)
pcre.error: ('missing )', 1)

(to catch the exception, use try/except re.error)
