I wanna give a -1 to this line.  This construction (x and y or z) and  
its pitfalls is actually the reason the ternary operator was added to  
python 2.5 and even after long discussions about what it means, I  
*still* find it confusing.

A 4-line if/else will cost you screen real estate but win you the  
love of your fellow man. :)
