json.decoder.JSONDecodeError:期望值:第1行第1列(字符0) [英] json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

问题描述

我正在尝试导入使用json.dumps保存并包含tweet坐标的文件:

I am trying to import a file which was saved using json.dumps and contains tweet coordinates:

{
    "type": "Point", 
    "coordinates": [
        -4.62352292, 
        55.44787441
    ]
}

我的代码是:

>>> import json
>>> data = json.loads('/Users/JoshuaHawley/clean1.txt')  

但是每次我收到错误消息:

But each time I get the error:

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

我想最终提取所有坐标并将它们分别保存到另一个文件中，以便随后可以对其进行映射，但这看似简单的问题却使我无法这样做.我已经看过类似错误的答案，但似乎无法将其应用于此.任何帮助将不胜感激，因为我是python的新手.

I want to end up extracting all the coordinates and saving them separately to a different file so they can then be mapped, but this seemingly simple problem is stopping me from doing so. I have looked at answers to similar errors but don't seem to be able to apply it to this. Any help would be appreciated as I am relatively new to python.

推荐答案

json.loads()采用 JSON编码的字符串，而不是文件名.您想改用json.load()(不使用s)并传入打开的文件对象:

json.loads() takes a JSON encoded string, not a filename. You want to use json.load() (no s) instead and pass in an open file object:

with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
    data = json.load(jsonfile)

open()命令生成一个文件对象，然后可以从中读取json.load()，以为您生成已解码的Python对象. with语句确保完成后再次关闭文件.

The open() command produces a file object that json.load() can then read from, to produce the decoded Python object for you. The with statement ensures that the file is closed again when done.

另一种方法是自己读取数据，然后将其传递到json.loads().

The alternative is to read the data yourself and then pass it into json.loads().
