Question

我正在使用json.loads以便将字符串中的列表转换为列表。（在数据传输过程中，列表将转换为字符串）。我收到异常：json.decoder.JSONDecodeError：预期值：第1行第43列（字符42）。

基本上，代码如下：

...

string_list = [["select", "What is your age?", [{"18+": True}, {"Below 18": False}], {"boolean": True}, {"application": ["basic", "all"]}, "age"], "18+", True]

replaced_str = str(string_list).replace("'",'"')

data = json.loads(replaced_str)

return data

...

奇怪的是，这个列表：

[["text", "What is your name?", {"question_application": ["basic", "all"]}], "utetwo"]

完美运行。

这是完整的错误回溯：

    Traceback (most recent call last):
  File "/usr/lib/python3.8/json/decoder.py", line 353, in raw_decode
    obj, end = self.scan_once(s, idx)
StopIteration: 42

During handling of the above exception, another exception occurred:

    raise JSONDecodeError("Expecting value", s, err.value) from None

我在其他地方找不到有关此问题的任何问题。我遵循了解决其他问题的所有步骤，但都没有成功。

尽管JSON正确，但奇怪的json.decoder.JSONDecodeError
