You are asking basic file layout questions in the learning process of
understand how to code in python.  Performance should be very low on
your list of concerns.  The only thing that happens when the file is
loaded is that it gets compiled, and run.  If it is imported, and you
have the 'if __name__ ... block, it will run the code within the if
block.  If that has a main() function it makes it simpler later to
change what main does instead of cluttering up the if block.  But
there is no 'performance' issue that I can see.
