My guess is you meant isalpha(), as Mark indicated. Here's a cheap way to
see what an object can do:

No, it's because you mispelled the variables.

Hi people.
I've got a small piece of code that I don't understand. Basically, a
variable inside an if statement inside a for loop doesn't seem to be
updating. Is this a scope issue ?

I didn't actually answer your question, my apologies!
The reason you're failing is due to your use of the __setattr__ call.
Remember, when you override __setattr__, you need to handle *all* of the
logic behind setting object attributes. You're only attempting to do so
when handling the 'name' pro
Thanks you Gabriel and Timm for your thoughtful responses. I am very

I had heard about the properties function, but wanted to understand

Perhaps you'd be better off using a standard property? Within your Person
class, you can define a property 'name' to handle what you're trying to do:

Because datetime is a new-style class:
The Constructor __new__
If you are like me, then you probably always thought of the __init__ method as
the Python equivalent of what is called a constructor in C++. This isn't the
whole story.
When an instance of a class is created, Python first calls the _

Thanks for all suggestions. Your first point I knew, but was too lazy to type

That should be pretty obvious: The UnboundLocalError comes up when you try
to access a variable that hasn't been assigned a value before. E.g try this

Hi,
I'm a bit stuck with this python script. It's aim is to encode all flac files
to wav and then to mp3. The only problem I have is to preserve the tags. The
code works when there's just one flac file in a directory but fails for more.
I can't see why the for loop fails here (flactags).
