It's also not sound in that it won't necessarily preserve the whitespace
in the middle. Usually this is undesired but there are times when it
can be useful to "normalize" a string, e.g.:
"This is an ugly string" becomes:
"This is an ugly string"
Of course it would be a bit more compact to use string member functions
(2.x):
def normalize_string(s):
return " ".join(s.split())
Anyhow, just thought I'd point this out. Sometimes bits of code that
don't do what they're intended to do end up doing something else that is
quite interesting in and of itself. :-)
