Is there a way to return literally nothing in python?

Question

I'm learning python and I was just wondering if I there was a way to write a code that does something like:

def f(x):
    if x>1:
       return(x)
    else:
        # don't return anything

I'm asking about the else part of the code. I need to not return anything if x<=1, returning None isn't acceptable.

There is no such thing as "returning nothing" in Python. Every function returns some value (unless it raises an exception). If no explicit return statement is used, Python treats it as returning None.

So, you need to think about what is most appropriate for your function. Either you should return None (or some other sentinel value) and add appropriate logic to your calling code to detect this, or you should raise an exception (which the calling code can catch, if it wants to).
