would not the more correct way to do this be short circuit
evaluation. somthing along lines of
if (len(item) > 0) and (item[0] == '-'): pass
seems to be the more correct approach. rather than relying on slicing
to return an empty string. For instance suppose you wanted to test to
see if th
Hello,
I'm a newbie to python. I run python under Manddrake Linux 10.2 from a
terminal.
While in the interactive mode, i need to use the tab key to indent my
code. However, i get a message "List all 174 possibilities? (Y/N)"
instead of an indent. So i use spaces.
How do i tell python to give me i
i think it is telling you to use spaces
btw i have no idea, it just sounds like a funny thing to happen

ahh, i hadn't thought of using a proirity queue but that is the correct
solution most of the time, except i suppose when you have input that
causes you to excessively reheap which could be problematic.
i may still look into writing a general sorted map though, it could be
useful especially if ther
It seems that the distinction between tuples and lists has slowly been
fading away. What we call "tuple unpacking" works fine with lists on
either side of the assignment, and iterators on the values side. IIRC,
"apply" used to require that the second argument be a tuple; it now
accepts sequences, a
