This is do_while or do_until. In Python, write it as do_until in this form.
while True:
value = get_some_value()
if value not in undesired_values:
break

The repetitiion is easily eliminated.
value = get_some_value() while value in undesired_values()
Forget this, or anything like it, as a 'serious' proposal.
