I'd caution against that, though.  It's clever and cute, sure, but the 
meaning of it is obfuscated enough to be unpythonic because [total > 0] 
as a subscript doesn't mean anything unless you know you're taking 
advantage of an implementation detail that booleans are 0 for false and 
1 for true.  No matter how reliable that fact may be, I don't think that 
value should be stuck into a numeric context like that.

This is much more clear, and would IMHO be fine.
