Yes, something like this is perfectly fine.
class ShoppingCart( object ):
def buy( self ):
print 'buy in shoppingcart'
class Buyer( object ):
def __init__( self, cart ):
self.cart = cart
def buy( self ):
print 'buy in buyer'
self.cart.buy( )
print 'some extra stuff'
acart = ShoppingCart( )
abuyer = Buyer( cart=acart )
abuyer.buy( )
