通过指针在Python中接收参数 [英] Receiving Arguments via Pointers in Python

问题描述

我有一个类，它的功能是这样定义的。我的本意是多个参数发送给它。

I have a class whose function defined like this. My intention is to send multiple arguments to it .

有关测试它，我把它叫做为：CLASS_NAME（参数1，参数2），它说，_ 的init 的_accepts atmost 1个参数，3给出

For testing it ,i called it as :class_name("argument1","argument2") , it says , _init_accepts atmost 1 arguments , 3 given

def __init__(self, **options):
    for name in options:
        self.__dict__[name] = options[name]

什么是处理这个问题的正确方法？

What is the proper way to handle this ?

任何建议表示欢迎......

Any suggestions welcome......

推荐答案

您想使用一个星号，而不是两个。双星号是命名参数。有蟒蛇文档中一个很好的解释的，如果你有兴趣阅读进一步。

You want to use one asterisk instead of two. Double asterisks are for named arguments. There is a nice explanation in the python documentation if you are interested in reading further.

def __init__(self, *options):
    for name in options:
        self.__dict__[name] = name

不过，从code，我认为，真正的问题是，你是不正确的呼唤你的功能。

However, from your code I think the real issue is that you are calling your function incorrectly.

您会怎么称呼它，如：

class_name(argument1="some value")

def __init__(self, **options):
    for name,val in options.iteritems():
        self.__dict__[name] = val
