How much sanity checking is too much in Python?
What happens if your extensive sanity checks turn up a bug?
In Python the usual answer is you raise an error:
raise ValueError('blahblah not a valid color')
What happens if you don't sanity check anything and the wrong color is
passed in?
Python will raise an error for you:
Traceback
...
KeyError: 'blahblah' not found

I sanity check for three reasons:
1) raise a nicer error message
2) keep the point of failure close to the error
3) the consequences of bad data are Bad Bad Things (tm)
If none of those apply, I don't bother sanity checking.
