如何使用双引号作为默认引号格式创建 Python 字典?

问题描述

我正在尝试创建一个 python 字典，该字典将用作 html 文件中的 java 脚本 var 用于可视化目的.作为必要条件，我需要使用双引号内的所有名称创建字典，而不是 Python 使用的默认单引号.有没有一种简单而优雅的方法来实现这一点.

 情侣 = [['杰克', '伊莲娜'],['阿伦'，'玛雅']，['hari', 'aradhana'],['比尔'，'萨曼莎']]对 = 字典(夫妇)打印对

生成的输出:

{'arun': 'maya', 'bill': 'samantha', 'jack': 'ilena', 'hari': 'aradhana'}

预期输出:

{"arun": "maya", "bill": "samantha", "jack": "ilena", "hari": "aradhana"}

我知道，json.dumps(pairs) 可以完成这项工作，但是字典作为一个整体被转换为一个字符串，这不是我所期望的.

P.S.: 是否有使用 json 的替代方法，因为我正在处理嵌套字典.

解决方案

您可以使用 json.dumps() 构建您自己的具有特殊打印功能的 dict 版本:

>>>导入json>>>类 mydict(dict):def __str__(self):返回 json.dumps(self)>>>夫妇 = [['jack', 'ilena'],['阿伦'，'玛雅']，['hari', 'aradhana'],['比尔'，'萨曼莎']]>>>对 = mydict(夫妇)>>>打印对{arun":maya"，bill":samantha"，jack":ilena"，hari":aradhana"}

你也可以迭代:

>>>对于 el 成对:打印电子阿伦账单杰克哈里

I am trying to create a python dictionary which is to be used as a java script var inside a html file for visualization purposes. As a requisite, I am in need of creating the dictionary with all names inside double quotes instead of default single quotes which Python uses. Is there an easy and elegant way to achieve this.

    couples = [
               ['jack', 'ilena'], 
               ['arun', 'maya'], 
               ['hari', 'aradhana'], 
               ['bill', 'samantha']]
    pairs = dict(couples)
    print pairs

Generated Output:

{'arun': 'maya', 'bill': 'samantha', 'jack': 'ilena', 'hari': 'aradhana'}

Expected Output:

{"arun": "maya", "bill": "samantha", "jack": "ilena", "hari": "aradhana"}

I know, json.dumps(pairs) does the job, but the dictionary as a whole is converted into a string which isn't what I am expecting.

P.S.: Is there an alternate way to do this with using json, since I am dealing with nested dictionaries.

解决方案

You can construct your own version of a dict with special printing using json.dumps():

>>> import json
>>> class mydict(dict):
        def __str__(self):
            return json.dumps(self)

>>> couples = [['jack', 'ilena'], 
               ['arun', 'maya'], 
               ['hari', 'aradhana'], 
               ['bill', 'samantha']]    

>>> pairs =  mydict(couples) 
>>> print pairs
{"arun": "maya", "bill": "samantha", "jack": "ilena", "hari": "aradhana"}

You can also iterate:

>>> for el in pairs:
       print el

arun
bill
jack
hari
