Basically I'm wondering if there are any plans to implemented named
loops in Python, so I can tell a break command to break out of a
specific loop in the case of nested loops.
See PEP3136 [1] and its rejection note [2]
I think you may find some more discussion in the python-ideas list.
Currently I'm using boolean
flag variables, but I find that very clumsy. I know this idea of
breaking out of specific loops from javascript; I guess java does it
too. It just seems a very Pythonian idea to me: clear, promotes code
legibility, seems obvious.
Although I've occasionally missed the feature myself, I agree with Guido's
arguments against it. You have several alternatives: refactor the loop
into an auxiliary function, use a specific exception, add boolean flags,
or repeat the test at the outer levels. (I usually choose the first).
