If run by an elf?  Who knows.  You do, of course, if you have learned
the basics of the language you are using.

It could also mean "if x was created on a Tuesday."  A short
introduction to the language explains what it actually means.

When did we come to the idea that people should be able to program in a
language without actually learning it?  The fact that Python comes so
close to that possibility is nothing short of revolutionary.  I suppose
one day a reasoning android will be able to sit down at the terminal of
a star ship computer and ask simple questions while making random hand
movements across a screen but for now I am afraid that programmers
still have to learn programming.
