JSONDecodeError Issue? python

Question

谁能帮我解决这个问题，我不知道为什么我得到这个错误。

我正在尝试使用别人做的python程序，我试着乱搞它，但我不能找出问题。

错误:

PS D:Python> python .quizlet.py
Traceback (most recent call last):
File "D:Pythonquizlet.py", line 69, in <module>
q = QuizletParser(website)
File "D:Pythonquizlet.py", line 17, in QuizletParser
data = json.loads(BeautifulSoup(session.get(link).content, features="lxml").find_all('script')[-6].string[44:-152])
File "C:UsersjohnAppDataLocalProgramsPythonPython39libjson__init__.py", line 346, in loads
return _default_decoder.decode(s)
File "C:UsersjohnAppDataLocalProgramsPythonPython39libjsondecoder.py", line 340, in decode
raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 1 column 14 (char 13)

我正试图使用我在这里找到的代码:https://github.com/daijro/python-quizlet

不看数据很难给出解决方案。

调试JSON错误的几个技巧:

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上添加逗号(这是很常见的)。
2. 检查数据类型。如果您的输入数据来自外部源，请先检查数据。

我建议把这个打印出来，如果可能的话贴在这里。

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