Well when you do something like

while x < 10:

it doesn't execute anything, but goes to newline and waits for the rest.

for
x = 10

what's the difference for you if it gets evaluated before or after?
Anyway you can you also %cpaste if you want to write more code

Anyway to me this works perfectly:
In [1]: x = 0

In [2]: while x < 10: print x; x += 1
   ...: 
0
1
2
3
4
5
6
7
8
9
