Python4Kids Blog: While

[ Thanks to Brendan Scott for this

“The structure of a while statement is:

while :
    

“The program answers the question: is the condition true or
false? If it is true, it does stuff in the section. When it is
finished it goes back up to the top and repeats the process again
and again until the condition is false:

>>> a = 10
>>> while a > 0:
...    a = a-1
...    print a
...
9
8
7
6
5
4
3
2
1
0

“The ordering here is a little odd because I forgot to print a in
the first line.”
