[Tutor] Help with functions

[Kirby Urner]

> That is my source code so far. I'm following the tutorial at http://www.honors.montana.edu/~jjc/easytut/easytut/node9.html

Something funny I found out is that it might work, but then when I quit python and open it again, it doesn't work, saying that ''length' is not defined'. Any thoughts??

If it works when you quit and go back into Python, it might be a reload issue.
If you're in the interpreter and make a change to a .py file in a text editor,
and save it, the interpreter will still operate with the old compiled .pyc
unless you force a recompile using reload(name_of_module).  

It's a little trickier if you don't import the module, but members of the 
module.  A workaround is to import the module as well, for the purpose of 
forcing a reload, and then reissuing the 'from xxx import a,b,c' command 
as before.  This can be done as a function itself.
