def printThese(a=None,b=None,c=None):
    print(a, "is stored in a")
    print(b, "is stored in b")
    print(c, "is stored in c")

def printScore(student,*scores):
    print(f"Student Name:{student}")
    for score in scores:
        print(score)

def printPetNames(owner,**pets):
    print(f"Owner Name:{owner}")
    for pet, name in pets.items():
        print(f"{pet}:{name}")


# 不能将**kwargs置于*args前

def printMytest(owner,*args,**kwargs):
    print("Owner:",owner)
    for i in args:
        print(i)
    for k,v in kwargs.items():
        print(f"{k}:{v}")


if __name__ == '__main__':
    # printThese()
    # printScore("jona",100,95,88,92)
    # printPetNames("Jonathan", dog="Brock", fish=["Larry", "Curly", "Moe"], turtle="Shelldon")
    printMytest("xxx",1,2,2,fruit="apple",ball=["basket","tennis","foot"],animal="cat")
