Hello, I have a code here that I’m having a problem with. It’s supposed to be a
pizza ordering simulator, as you can tell by the title, but I keep trying to
add music to it and whenever I try to play the music with the program running,
it always freezes up and crashes. Can someone help me with t

Unfortunately we can't see it.
Now, I could see it among a bunch of HTML when I checked it in the
moderator queue, so I'm guessing you sent it as some kind of

Hi list,
I've read three or four articles on creating decorators. I don't know why,
but the use of decorators makes sense, yet the creation of them isn't
clicking. I get the idea, but when it comes to precisely how to write
one--what goes where and gets returned/called when--it's just not making

Sorry for top posting, but yes excepting you don't need the parens after
log in the @log line.

Okay, I think I follow. So a decorator to log that a function ran might
be:

For decorators, do you never include parentheses except for passing
arguments? It seems a bit odd to drop them if they'd be empty, given that

I think you'll find that for-loops are preferable to while-loops. Here's an
alternative implementation.

Hi all,
Thanks for all the help regarding decorators. It makes more sense now.
I was double checking that I remembered the isinstance order of arguments
correctly by using the command line interpreter, and found something very
odd.
>>> a = 5
>>> isinstance(a, int)
True
>>> a is int
False

Ooops, I meant to say
func = decorator()(func)
Sorry.

'isinstance' is something else from 'is'.
isinstance will tell us if something
hey everyone. this is my first time trying this -- actually, I've been

to be rally simple, but I can't seem to understand this piece of code and
thus can't move on.

You're probably thinking of "is a", as in, "5 is an int", "'Hello

Hi Heloisa, and welcome.
Do you have a link to the code? Or better still, if it is short (say
under fifty lines) can you copy it into an email and send it?
