It doesn't return anything, it prints something out.
Printing something out from within a function is not the same as
returning something.
Consider the following::
def nonsense( something ):
print( "something is", something )
return ( 5, "elephants", { "monkey": "peanut", "baboon":
"banana", "numbers": ( 1, ), }, [ 1, 2, 3, 4, 5,
"mouse",( -6.34565e-35, 4.765213e84, ), ],
None, True, False, )
print( "nonsense( 10 ) is", nonsense( 10 ) )
print( "nonsense( None ) is", nonsense( None ) )
print( "nonsense( ( 5, \"donuts\", ) ) is", nonsense( ( 5, "donuts", ) ) )
The above code shows there is no automatic connection between data output
carried out within a function and the value (if any) returned by that
function.
