why does this work? "while p" = "while p != 0" ? 1 is True and 0 is
false in python but other numbers have no boolean value so why doesnt
it abort.
p=16
p

while p:
print p
p -= 1

i can also do:
k=[]
while k:
k.pop()
k=[1,2,3]
while k:
k.pop()
3
2
1
so obv while var means while not empty or why not zero but it isnt
something youd guess unless youd beeen shown it.
Python manuals outline that 0, None, empty list, empty dictionary are False
anything else evaluates to True. This is all over this list as well.
