-------------------
Hi,
When running the tokenize example at the bottom of http://docs.python.org/py3k/library/re.html#match-objects
I received the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 23, in tokenize
NameError: global name 'val' is not defined
The problem is that val is never assigned to before this line:
if typ == 'ID' and val in keywords:
Here is a suggested rewrite of the that section:
elif typ != 'SKIP':
val = mo.group(typ)
if typ == 'ID' and val in keywords:
typ = val
yield Token(typ, val, line, mo.start()-line_start)
Attached is a complete working example.
