使用用户输入命名列表 [英] Naming Lists Using User Input

问题描述

我想让用户定义代码中要使用的列表的名称，因此我一直在使用输入函数.我希望用户对输入功能的响应成为列表的名称.我尝试了以下方法:

  a =输入(您希望列表的名称是什么?")a = [] 

但是，此命令将列表命名为"a"，而不是用户对输入函数作出响应的任何字符串.如何让用户为列表命名?反正有这样做吗?

解决方案

在此处完成所需操作的正确方法是列表的 dict :

 >>>列表= {}>>>清单['家庭作业'] = [40、60、70]>>>list ['tests'] = [35，99，20]>>>清单{测试":[35、99、20]，作业":[40、60、70]}>>> 

当您可以请求输入时， input 函数(在Python 2.x中为 raw_input )返回一个字符串，您可以将该字符串作为字典的键./p>

I would like to let the user define the name of a list to be used in the code, so I have been using an input function. I want the user's response to the input function to become the name of the list. I tried the following:

a = input("What would you like the name of the list to be? ")
a = []

However, this named the list "a" rather than whatever string the user had responded to the input function. How can I let the user name the list? Is there anyway to do this?

解决方案

The correct way to accomplish what you want here is a dict of lists:

>>> lists = {}
>>> lists['homework'] = [40, 60, 70]
>>> lists['tests'] = [35, 99, 20]
>>> lists
{'tests': [35, 99, 20], 'homework': [40, 60, 70]}
>>> 

When you can ask for input, the input function (raw_input in Python 2.x) returns a string, which you can make the key of the dictionary.
