They both look silly to me, though. The DRY principle applies to objects too...

Why? It's not like you have to look at the filenames before you pass them to an API function...
"someFunc(x.strip() for x in z if x.strip())" was just an example.
Have you never used a list comprehension as a filter/processor to handle an iterable you are passing into a function ?
If the alternative is creating another interface to the function, this way causes less repition.
"It's not like you have to look at the filenames" - unless you present them back to the user for example. Under what circumstances would you *not* want normpath called ?
