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
16
>>> while p:
print p
p -= 1
16
15
14
13
12
11
10
9
8
7
6
5
4
3
2
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.
