函数里可以当做元组读取可变参数

例子：

def tupleVarArgs(arg1,arg2='defaultB',*theRest):
    print 'formal arg 1:',arg1
    print 'formal arg 2:',arg2
    for eachXtrArg in theRest:
        print 'another arg:',eachXtrArg

>>> tupleVarArgs('abc')
formal arg 1: abc
formal arg 2: defaultB
>>> tupleVarArgs(23,4.23)
formal arg 1: 23
formal arg 2: 4.23
>>> tupleVarArgs('abc',123,'xyz',344.23)
formal arg 1: abc
formal arg 2: 123
another arg: xyz
another arg: 344.23
>>>
