The idiomatic way in Python of writing a non-terminating while-loop is:
while 1:
or the (
slightly slower) alternative:
while True:
I saw a suggestion on the Python mailing list that I really like, which relies on the behaviour that non-empty strings are evaluated by conditions to be True and provides a self-documented truth-condition, which can note why the loop is non-terminating or what the break condition is.
while "the program is running":
...
while "data is still streaming":
....
while "no one presses escape":
