How much sanity checking is required for function inputs?

Because the example I found used it, I implemented it, and it worked in 
my code. Based on feedback that I gotten from this list, I'll go back 
and clean it up.

I found it on the Internet, so it must be true -- and Pythonic at that!

Keep in mind that I'm coming from a Java background (not by choice) with 
a smattering of C programming. I initially had ALL THESE CONSTANTS in 
different parts of my code and couldn't easily use them across different 
modules. I didn't like all these constants, created a singleton class 
that uses ConfigParser, dumped everything into a .ini file, and accessed 
from in each module. As I learn to write Pythonic code, the constants 
may go away. Switching from my original code to the factory method 
eliminated a half-dozen constants.

Thank you,
