问题描述
我记得我曾经见过一个能够在python中分解列表的运算符.
I remember I once seen a operator which is able to decompose a list in python.
例如
[[1],[2],[3]]
通过应用该运算符,您将得到
by applying that operator, you get
[1], [2], [3]
该操作员是什么,任何帮助将不胜感激.
what is that operator, any help will be appreciated.
推荐答案
如果要将参数列表传递给函数,则可以使用splat运算符*
.运作方式如下:
If you want to pass a list of arguments to a function, you can use *
, the splat operator. Here's how it works:
list = [1, 2, 3]
function_that_takes_3_arguments(*list)
如果要将列表的内容分配给变量,则可以列出解压缩列表:
If you want to assign the contents of a list to a variable, you can list unpacking:
a, b, c = list # a=1, b=2, c=3
