I didn't test that particular part..  but this should work.  It wasn't
the fault of the formatting. ;-)

def f(a,b,x=None,y=None):
    return 1
    
def g( args,x=None,y=None,foo=None):
    return 1

args_from_somewhere = (23,24)

y = f(11, 22, x=1, y='y for f') 		\
         * g( args_from_somewhere,
              x='x for g', 
              y='y for g',
              foo=lambda foo: 'foo for g' )

print y
