TypeError: cannot unpack non-iterable NoneType object Error ('Expecting value: line 1 column 1 (char 0)',)

TypeError: cannot unpack non-iterable NoneType object 是一个 Python 错误，表示尝试对一个不可迭代的 NoneType 对象进行解包操作（例如使用多个变量来接收函数返回的结果，但是函数返回了 None 而不是可迭代对象）。这通常意味着在代码中出现了一些错误。

而 'Expecting value: line 1 column 1 (char 0)' 这个错误则是在使用 JSON 解析器时出现的错误，通常是由于提供的字符串不是有效的 JSON 格式所致。

如果你遇到这个错误，可以检查代码中与解包和 JSON 解析有关的部分是否存在问题，也可以检查提供的字符串是否符合 JSON 格式要求。

TypeError: cannot unpack non-iterable NoneType object

This error message usually occurs when you are trying to unpack a variable that is None or has a value of NoneType. The unpacking operation requires an iterable object, such as a list or a tuple, but None is not iterable, hence the error.

For example, consider the following code:

x, y = None

Here, we are trying to unpack the value of None into two variables, x and y. Since None is not iterable, Python raises a TypeError with the message "cannot unpack non-iterable NoneType object".

To fix this error, you need to make sure that the variable you are unpacking is not None. You can add a check to ensure that the variable has a value before unpacking it, or provide a default value to use when the variable is None.

For example:

values = [1, 2, 3]
x, y = values if values else (0, 0)

Here, we are unpacking the values list into two variables, x and y. If the values list is empty, we provide a default value of (0, 0) to avoid the NoneType error.

typeerror: cannot unpack non-iterable nonetype object

"TypeError: cannot unpack non-iterable NoneType object" 的意思是，在代码中尝试将一个 NoneType 类型的对象解包（unpack）为多个变量，但是 NoneType 类型的对象是不可迭代的，因此无法解包。这通常意味着在该行代码之前，未正确地返回一个可迭代对象。
