关于python的函数调用传递的参数前面的*

调用（caller）

func(*sequence) Pass all objects in sequence as individual positional arguments

seq = [1,2,3]

func(*seq) -> func(1, 2, 3)

func(**dict) Pass all key/value pairs in dict as individual keyword arguments

dict = {'a' = 1, 'b' = 2}

func(*dict) -> func(a = 1, b = 2)

函数定义的

def func(*name) Matches and collects remaining positional arguments in a tuple

func(1, 2, 3) -> name = [1, 2, 3]

def func(**name) Matches and collects remaining keyword arguments in a dictionary

func(a = 1, b= 2) -> dict = {'a' = 1, 'b' = 2}
