Ruby and Smalltalk are both good at this kind of thing, since they have
syntactic support for associating a block with each method call. In
Python, I think you just have to do a little more setup. How about
something like this?
class Loop:
def __init__(self, n):
self.n = n
def __call__(self):
self.n = self.n - 1
return self.n != 0
if __name__ == '__main__':
loop = Loop(10)
while loop:
print "OK"
