用 Python 编辑 Json 文件？ [关闭]答案

【问题标题】：Edit Json file With Python? [closed]用 Python 编辑 Json 文件？ [关闭]
【发布时间】：2018-07-18 20:54:39
【问题描述】：

我是 python 新手。也从不使用 JSON。我有一个 json 文件，由于第 8 行中缺少“，”而无法打开。所以如何用 python 解决这个问题。我知道如何使用 python json lib 处理 JSON 文件中的缺失值。

我将 python3 与 ipython 一起使用

我使用的python脚本：

import json

with open('name_dob_height.json') as json_file:
d = json.load(json_file)
print(d)

最后一行错误消息：

JSONDecodeError: Expecting ',' delimiter: line 8 column 3 (char 109)

json_file =

【问题讨论】：

对于 json 文件，您必须使用 json 模块。谷歌一下，你会找到的。
@Narendra 看起来 OP 已经在使用 json 模块了
第一个对象之后，JSON文件中没有逗号。请添加逗号它会解决您的问题。
@kvk30 我可以手动执行此操作。我用python程序去了
@NajeebChoudhary 具有正确的 Json 格式，这是不可能的。

【解决方案1】：

我在您的代码中看到您的JSON 文件中缺少分隔符。您可以在第 8 行添加分隔符。完成此操作后，json 文件可以毫无问题地打开。在代码中没有问题。

【解决方案2】：

请更新您的 JSON 文件，它会对您有所帮助。在检查任何 JSON 文件之前，请在此链接中验证，JSON validator

json_file =

    [
    {
        "First_name": "Nathan",
        "Last_name": "Astle",

您的 JSON 中有错误。请使用更正后的 json：

[{"First_name":"Nathan","Last_name":"Astle","Date_of_birth":"1971-05-18","Height":"155"},{"First_name":"Nathan","Last_name":"Astle","Date_of_birth":"1971-05-19","Height":"155"},{"First_name":"Arthur","Last_name":"Harrison","Date_of_birth":"1982-01-29","Height":"168"},{"First_name":"Cameron","Last_name":"White","Date_of_birth":"1982-01-29","Height":"170"},{"First_name":"Steve","Last_name":"Finn","Date_of_birth":"1971-05-18","Height":"189"},{"First_name":"Elliot","Last_name":"Luca","Date_of_birth":"1971-05-18","Height":"172"},{"First_name":"Methews","Last_name":"Haiden","Date_of_birth":"1971-05-18","Height":"165"},{"First_name":"John","Last_name":"Smith","Date_of_birth":"1971-05-18","Height":"invalid string"},{"First_name":"Daniel","Last_name":"Clerk","Date_of_birth":"1971-05-18","Height":"190"},{"First_name":"Allan","Last_name":"Hernandez","Date_of_birth":"1981-01-19","Height":"178"},{"First_name":"Harley","Last_name":"Smith","Date_of_birth":"1988-05-21","Height":"185"},{"First_name":"Nathaniel","Last_name":"Stewert","Date_of_birth":"1980-08-10","Height":"125"},{"First_name":"Michael","Last_name":"Johnson","Date_of_birth":"1990-03-26","Height":"152"}]

即您在 JSON 中的第一个对象之后缺少逗号 ,

【讨论】：

是文件在第 8 行缺少逗号

【解决方案4】：

使用模块 JSON

import json

with open('your_file.json') as json_data:
    d = json.load(json_data)
    print(d)

【讨论】：

问题是缺少逗号。 OP 已经在使用 json
你的假设是错误的，他使用的是 JSON 模块。如果他不使用它，那么它会引发另一个错误。
他表明他有 json 文件并想通过 python 脚本读取它对吗？
是的，但是 JSON 的架构是错误的。
