Calling a 5-argument function with a completely different set of arguments each time is pretty rare. If, in practice, you're using the same a, c, and e args most of the time and calling with different b and d args (for example), you can create a class to help you with this:
class FooWrapper(object):
def __init__( self, commonA, commonC, commonE ):
self.a = commonA
self.c = commonC
self.e = commonE
def invokeFoo( self, _b, _d ):
foo( a=self.a, b = _b, c = self.c, d = _d, e = self.e )
w = FooWrapper( 1, 2, 3 )
w.invokeFoo( 4, 5 ) # calls foo( 1, 4, 2, 5, 3 )
w.invokeFoo( 6, 7 ) # calls foo( 1, 6, 2, 7, 3 )
