Nothing, until you run that with some particular version of Python. If 
you do run it, the result should be as documented for that particular 
version. If you write additional code to call the function, the result 
will depend on the Python version and argument.

Now, what did you actually want to know ;-?
You should likely find the answer in the reference manual, especially 
the section on def statements.
