Did the first riddle also, very nice way to revise regular expressions!

I’ll leave the second one for later but reading the description, I am  
puzzled by a definition:

def cypher(text, keyword, direction=1):  
if direction \< 0: direction = -1  
else: direction = 1It looks like the direction will never alternate  
between 1 and -1. I suppose this is a bug, isn’t it?  
Thanks anyway, your riddles have a “I-want-to-know-whats-next” flavor.

For those interested in **programming riddles** , I would like to  
announce a new programming challenge I’m just launching at

This challenge is in its early stage and thus set to be continuously  
improved.

I would be especially interested in your comments and feedbacks about  
this initiative and its relevance.

Enjoy!
