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")

功能一样,可见**args 时应为字典类型,或是关键字类型的参数。
