Question

我需要将输出写入python中的json文件。我在这里尝试了一些答案来写入json文件，但是由于某种原因，我找不到正确的格式，因此我需要将数据写入json文件。

我正在看的是：

'#fiche?username=' + username

如何用python编写这种格式？

谢谢

Answer 1

首先，您的“ json”是错误的。我假设外部花括号应为方括号，因此您尝试保存列表。集合不是json格式的一部分。假设不是this answer所不想要的，因为输出未格式化，则可以根据需要使用the documentation来格式化文件。例如：

Python 3.7.0 (default, Nov 21 2018, 10:19:24) 
Type 'copyright', 'credits' or 'license' for more information
IPython 7.1.1 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import json                                                                                            

In [2]: obj = [{ 
   ...:   "Region": "BD", 
   ...:   "name": "bdfe", 
   ...:   "tyl": "cya", 
   ...:   "ice": "messi", 
   ...:   "fed": "bet", 
   ...:    }, 
   ...:    { 
   ...:   "Region": "Toron", 
   ...:   "name": "Cana", 
   ...:   "tyl": "cyab", 
   ...:   "ice": "feed", 
   ...:   "fed": "not", 
   ...:    }]                                                                                                  

In [3]: with open('data.json', 'w') as outfile: 
   ...:     json.dump(obj, outfile, indent=4) 
   ...:                                                                                                        

In [4]: !cat data.json                                                                                         
[
    {
        "Region": "BD",
        "name": "bdfe",
        "tyl": "cya",
        "ice": "messi",
        "fed": "bet"
    },
    {
        "Region": "Toron",
        "name": "Cana",
        "tyl": "cyab",
        "ice": "feed",
        "fed": "not"
    }
]

在python中复制该代码非常简单。您所要做的就是将其转换为字典。这是转换后的输出：

import json


mydict = [{
"Region": "BD",
"name": "bdfe",
"tyl": "cya",
"ice": "messi",
"fed": "bet",
 },
 {
"Region": "Toron",
"name": "Cana",
"tyl": "cyab",
"ice": "feed",
"fed": "not",
 }]

with open('data.json', 'w') as out: 
    json.dump(mydict, out, indent = 2)

在python中以特定格式写入json文件
