'foot' controlled loop in python ??

[Axel Kowald]

Hi,
I got recently into Python and I like it a lot. However, I haven't found 
a loop contruct that is 'foot' controlled, i.e. something like 'do 
until' or 'repeat while'. Am I overlooking something or is there no such 
thing ?

And if not maybe that could be a suggestion for Python 2.3 ?? Often I 
want to enter a loop at least once and can only decide if  I want to 
continue when I'm inside the loop. Without a 'foot' controlled loop it's 
somewhat awkward to program such a behaviour.
