ing at a moving target.
How about:
newlist = (
[x for x in mylist if x.startswith(key)] +
[x for x in mylist if not x.startswith(key)]
)
return newlist
Or if you really insist on mutating the original list (which seems less
clean to me, but you do you), then:
newlist = blahblahblah
y point. All (well-behaved) iterators are iterables,
with their __iter__ method returning themselves.
for x in y:
...
implies:
try:
_it = iter(y)
while True:
x = next(_it)
...
except StopIteration:
pass
That's true for any iterable y, including a y which is itself an
iterator.

Don't know which one is line 42; but I'd bet your problem is there.
As a rough guess, it might be the line that says:
pizza_cost = pizzatype[menu]
You're bounding that to the range 1-5. A Python list of length 5 has
indices 0-4.
But the error message is telling you everything you need to know; you're
trying to get a list index that's out of range in line 42. Find line
42, figure out what index you're asking it for, and you'll have your
answer. If you don't have an editor that shows you line numbers then
your editor is fundamentally terrible and you should not use it (I
personally like Notepad++ for Windows or Geany for Linux).

creating.
Also, as a mailing list/Usenet etiquette note: You get to have one name
you go by. Going around changing the name you're posting under in the
middle of the thread is a guaranteed way to piss folks off. You didn't
know. You now do.

Just read on Usenet instead of through the mailing list. That way
you can accept broken threading as a given rather than wonder why it's
happening in a particular case.

print list(block['relative_chart1']['vessel_names']) should work.

Does anyone know the history of why relative imports are only available
for packages and not for "programs"? It certainly complicates life.
