How to declare a function "to do nothing" in Django

Question

I'm learning Python and Django and I have a question.

I would like to know how to define a function that does nothing and continue with the flow of program execution while I read an archive.

while True:
     empty()
     with open(r'archive.txt') as myfile:
        for line in myfile:
            print(line)

How I can write a function that does nothing like for example:

def empty():

i dont want pass parameters to the function just for the flow of the program continues without a break. — ymd_, Oct 20 '16 at 15:24
What's the point of this? Why call the function at all if you don't want it to do anything? — Daniel Roseman, Oct 20 '16 at 17:05

If you're using Python 2.x:

def empty():
    pass

With Python 3.x you can also do this:

def empty():
    ... # this is called Ellipsis, simply three dots in a row
