JavaScript的参数对象的python版本 - 它存在吗? [英] python version of javascript's arguments object - does it exist?
问题描述
参数
预定义对象,它保存有关传递给函数调用的参数的信息,例如 function test(){
var args = Array.prototype.slice.call(arguments);
console.log(args);
}
参数可以轻松转储到标准数组中:
test()
// []
test(1,2,3)
/ / [1,2,3]
test(hello,123,{},[],function(){})
// [hello,123,Object ,数组[0],函数]
我知道在Python中我可以使用标准参数,和关键字参数(就像定义的这里)来管理动态参数号 - 但是在Python中有没有类似于 arguments
对象的东西?
它不像python中的那样存在,但是你可以调用locals()作为函数中的第一件事,并且在那一点上它应该只有参数
>>> def f(a,b):
... args = locals()
... for arg,args.items()中的值:
... print arg,value
...返回a * b
...
In JavaScript each function has a special arguments
predefined objects which holds information about arguments passed to the function call, e.g.
function test() {
var args = Array.prototype.slice.call(arguments);
console.log(args);
}
arguments can be easily dumped to a standard array:
test()
// []
test(1,2,3)
// [1, 2, 3]
test("hello", 123, {}, [], function(){})
// ["hello", 123, Object, Array[0], function]
I know that in Python I can use standard arguments, positional arguments and keyword arguments (just like defined here) to manage dynamic parameter number - but is there anything similar to arguments
object in Python?
It doesnt exist as is in python but you can call locals() as the first thing in the function and at that point it should only have the arguments
>>> def f(a,b):
... args = locals()
... for arg, value in args.items():
... print arg, value
... return a*b
...
