def cheeseshop(kind,*arguments,**keywords):    print("-- Do you have any",kind,"?")    print("-- I'm sorry, we're all out of",kind)    for arg in arguments:        print(arg)    print("-"*40)    keys = sorted(keywords.keys())    for kw in keys:        print(kw,":",keywords[kw])f={"client":"John","sketch":"cheese"}cheeseshop("Limburger","aaaaaaa","bbbbbbbbbb",**f)

cheeseshop("Limburger","aaaaaaa","bbbbbbbbbb",client="John",sketch="cheese")
