:No, in some other languages it might be legal, but this is Python.
:without the parentheses it is a syntax error.

This discussion leads me to this question:

Is it possible for python to allow free splitting of single-line statements
without the backslashes, if we impose that expressions can only be split
when it is not yet a finished expression? Note: splitting before closing 
parenthis, brace, or bracket can be viewed as special case of this 
more general rule.
