When I use languages that supply do-while or do-until looping constructs I rarely need them. I personally miss for init; condition; next: more than do-while, but the structured for loop doesn't fit in Python since init and next would (probably) have to be statements (or statement suites) rather than expressions. Hence, the cool innovations of iterators and generators, which otherwise might not have found a home in Python. I wonder what programming Python was like before iterators sometimes. However, did you have an specific need for a do-while construct? Perhaps we could show you the alternatives. -- Neil Cerutti -- http://mail.python.org/mailman/listinfo/python-list
