获得；TypeError:字符串索引必须是整数；用python打印时；包含数量和单位的列表字典

我有test.txt文件（如下所示）

当我试图打印时，我得到了这个错误

>>> print(content['mass']) 
Traceback (most recent call last):  
 File "<stdin>", line 1, in <module>
TypeError: string indices must be integers

工作正常，并显示全部内容（test.txt）

我需要打印dict中的每个列表（如质量、温度等），并绘制其中的任意两个

文件内容如下：

{'mass': <Quantity [0.01066337, 0.05677534, 0.01377424, 0.06982872, 0.02665362] solar_mass>, 'temperature': <[values ... ] unit>}

{'mass'：，'temperature'：}

{'mass'：，
‘年龄’：，‘温度’：，‘重力’：，‘光度’：，‘半径’：}

试试这个：

import json

json_data = json.loads(content)

print(json_data["mass"])

内容

是字符串，而不是字典。我想您需要首先解析它。“TypeError:字符串索引必须是整数”这意味着它听起来就是这样。如果您被告知用于字符串的索引有问题，这意味着您要索引的对象是字符串。您为这本

词典

添加了标签，这意味着您希望将其索引到词典中。您拥有的字符串看起来像字典的语法，但它仍然不是字典。你必须做字典。真正的问题是为什么你的文件看起来像这样？似乎您想象过，您可以盲目地将任何数据结构的字符串表示形式写入文件中，然后再读取它并获取数据结构。它不是这样工作的，首先是因为不是每个对象都是为它设计的，其次是因为您仍然需要告诉Python字符串表示其他内容。其他人无法告诉您如何处理这些数据，因为

表示代码中我们看不到的内容。您需要从头开始并解释整个问题，包括向我们展示原始数据来源的代码，以及解释您希望通过创建文件来解决的问题。代码可用，但文档有点不符合最新的更改。一般来说，如果模拟的输出类似于{'mass'：，'temperature'：}，我可以只单独打印列表，还是必须修改输出以使其工作？？？OP的文件内容不是有效的JSON。

import json

json_data = json.loads(content)

print(json_data["mass"])
