ignoring a part of returned tuples

[noamtm]

Hi,

Some functions, like os.walk(), return multiple items packed as a
tuple:

for (dirpath, dirnames, filenames) in os.walk(...):

Now, if you don't care about one of the tuple members, is there a
clean way to ignore it, in a way that no unused variable is being
created?

What I wanted is:
for (dirpath, , filenames) in os.walk(...):

But that doesn't work.

Thanks, Noam.

That's what I need - this avoids PyLint telling me that I have an
unused variable, and also makes it clear that this value is not used.

Thanks!

Thanks, that's even better!

Noam.
