Python函数中的可变参数定义方法以及参数的传递方法解析

def func(*args, **kwargs):

  print args

  print kwargs

>>> func(1,2,3)

(1, 2, 3)

{}

>>> func(*[1,2,3])

(1, 2, 3)

{}

>>> func(a = 1, b = 2, c = 3)

()

{'a': 1, 'c': 3, 'b': 2}

>>> func(**{'a':1, 'b':2, 'c':3})

()

{'a': 1, 'c': 3, 'b': 2}

>>> func(1,2,3, a = 4, b=5, c=6)

(1, 2, 3)

{'a': 4, 'c': 6, 'b': 5}</span>

 #这样跳跃传递是不行的

>>> func(1,2,3, a=4, b=5, c=6, 7)
