That's painfully inconsistent.

No, I thought I had.

>>     print "You have $%0.2f bucks" % ((4.5/100,) * 2)
>This, on the other hand is wrong since ((4.5/100,) * 2) yields (0.045,

Typo.

Thanks for nothing: there are no manpages.  I read the Lutz book.
You'll note that I even MENTIONED this issue in a gotcha.
It's just easy to get tripped up by the inconsistency.

You seem to be looking for a fight.   Please say nothing
at all if that's all you want to do.
