This is the silliest thread I've ever seen in this group.  I should
abstain, but what the heck:

If you want a function that does nothing, write one.  Maybe like this:

def do_nothing():
    return

Then, where you previous wrote pass in your code you can replace it
with this thing.

But really, not being a language meta-maven myself, somewhere above in
this thread it was pointed out that pass is a syntax construction that
is necessary in the very seldom case where you create a block of code
that has no instructions.  Instead of braces for every block, you get
to skip that in python and just put pass in this extraordinary little
case.

While I've come to the point in my python coding knowledge to get my
day to day work done proficiently, I'm amazed each time I delve deeper
into how profoundly well this language was thought out.  No offence to
all the well meaning participants here, but this looks like trolling
