New submission from Ângelo Otávio Nuffer Nunes <angelonuf...@gmail.com>:
When I use the scanner object in re module, I can create groups on regex and
associate this to a method...
In [17]: re.Scanner([(r"(\w)(\w)\w", foo)])
Out[17]: <re.Scanner instance at 0x15c4e60>
But I tryed 3 groups and it raises "invalid SRE code", but I think my regex is
not wrong...
In [15]: scan = re.Scanner([(r"(\w)(\w)(\w)", foo)])
