> can't use print x anymore

Yes, its a function not a statement, so its now print(x).

> which also gets rid of "print x,", which printed something without making a newline, for one thing.

Sure, you have to do: print(x,end=' ')

if you want to space separate things printed on separate code lines on the same output line.

Of course, if the extra keystrokes bother you, its really not much one-time cost to toss together a library that provides a function that gets rid of them, while keeping the rest of the power of the print function:

    def p(*args, **kwargs): 
        kwargs = {'end': ' '}.update(kwargs)
        print(*args,**kwargs)

Though if I was going to bother to do that, I'd probably do it with the same separator for multiple items on the same line as for items on different lines:

    def p(*args, **kwargs): 
        kwargs = {'sep': ' ', 'end': ' '}.update(kwargs)
        print(*args,**kwargs)

or, further leveraging print-is-a-function:

    import functools

    p = functools.partial(print, sep=' ',end=' ')

  print(x, end='')

Not quite as nice, but not exactly unusable.

It's a lot less "pythonic".

Dunno. The 3 way is more "Explicit is better than implicit." Though it's a shame Python 3 messes up http://xkcd.com/353/
