?? AFAIK there is only one meaning for KeyError - the key was not found
in the dict. From the docs: "Raised when a mapping (dictionary) key is
not found in the set of existing keys."

Yes, classes are just objects and their attributes are too.

Test.foo = f

Greetings,
I think the accepted way to get help on this list
is to post the code you're having problems with,
showing what you've done, the error messages
you're getting, and an explanation of what you're
trying to do, the input, output expected, and so
forth. It is helpful for the Tutors to also

If a line in a script has

It's simple to convert the string, "1,987,087,234,456" to an int, but
I can't figure out how to do it for
n = 1,987,087,234,456 # no quotes

now if you had asked about the meanings of *all* exceptions (including

What's that asterisk doing in decomma(*t)? Where do I go in the docs

Thanks,

I am a newbie but think its for variable input. Allows you to enter any number
with commas in it and still work properly. Since it thinks the number is a
tuple, then depending on the number your tuple could vary in length.
