Thank you for the reply. I was really thinking of some function in the
standard library like:
s = stripUnprintable(s)
When I learned php, I more or less took the route of using whatever I
found that 'worked'. In learning Python, I'm trying to take my time and
learn the 'right' (that's pronounced 'beautiful') way of doing things.
As it stands, I've stashed the string.translate code in a short function
with a comment explaining what it does and how. I mainly didn't want to
use that if there was some trivial built-in that everyone else uses.
