Tell a penguin that it can fly :-)
Yeah ok :) But the ancestors of penguins didn't wake up one morning, flap
their wings and fall out the tree, it happened gradually. Python2 syntax
could have been retained for X versions of 3 just as C++ keeps old stuff
until its eventually deprecated them removed.
Yeah? So what would this do:
print ()
In Python 2 this prints an empty tuple.
In Python 3 this is a call to the print function with no arguments,
which prints a blank line.
You can't have it both ways.
In any case, supporting two different syntaxes simultaneously would be
messy and difficult to maintain.
Better a clean break, with Python 2 support continuing for a long time
(as it was).
