Python 中的 *args 和 **kwargs

带有这种参数的，实际传入参数时可以有多个，案例如下：

def helloPython(*args,**kwargs):
    print ("non-key arguments are:")
    for a in args:
        print (a)
         
    print ("key-value arguments are:")
    for k,w in kwargs.items():
        print (k+"="+w)
 
helloPython("I","know",whom = "you",what = "understand")
