JSONDecodeError 问题？ Python

Question

谁能帮我解决这个问题，我不知道为什么会出现这个错误。

我正在尝试使用某人制作的 python 程序，我试图弄乱它，但我无法找出问题所在。

错误：

PS D:\Python> python .\quizlet.py
Traceback (most recent call last):
  File "D:\Python\quizlet.py", line 69, in <module>
    q = QuizletParser(website)
  File "D:\Python\quizlet.py", line 17, in QuizletParser
    data = json.loads(BeautifulSoup(session.get(link).content, features="lxml").find_all('script')[-6].string[44:-152])
  File "C:\Users\john\AppData\Local\Programs\Python\Python39\lib\json\__init__.py", line 346, in loads
    return _default_decoder.decode(s)
  File "C:\Users\john\AppData\Local\Programs\Python\Python39\lib\json\decoder.py", line 340, in decode
    raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 1 column 14 (char 13)

我正在尝试使用我之前在这里找到的代码：https://github.com/daijro/python-quizlet

不看数据很难给出解决方案。

调试 JSON 错误的一些技巧：

1. 检查 JSONDecoder 的输入数据。您可能会在输入字典的最后一个键值对中添加一个逗号（这很常见）。
2. 检查数据类型。如果您的输入数据来自外部来源，请先检查数据。

如果可能的话，我建议打印并粘贴到这里。

input_data = BeautifulSoup(session.get(link).content, features="lxml").find_all('script')[-6].string[44:-152]
print(input_data)
