JSONDecodeError是一个解析JSON数据时可能遇到的错误。错误消息"Expecting property name enclosed in double quotes: line 1 column 41 (char 40)"表示JSON数据在第1行第41列(字符40)处期望一个双引号括起来的属性名。
出现这个错误的原因是JSON数据中的属性名没有使用双引号括起来。在JSON中,属性名必须以双引号括起来,而不是使用单引号或者没有引号。例如,错误示范是{'k1':v1,'k2':v2},正确示范是{"k1":v1,"k2":v2}。
要解决这个问题,你可以确保在JSON数据中的属性名都被双引号括起来。你可以使用json.dumps()函数将Python的字典对象转换为符合JSON规范的字符串,然后将其写入JSON文件。例如,正确的做法是使用以下代码:
```python
import json
data = {"k1": v1, "k2": v2}
with open('xxx.json', 'w') as fw:
fw.write(json.dumps(data))
```
这样,你就可以避免JSONDecodeError错误,并正确地解析JSON数据了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
