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 occurs when you try to unpack a variable that is of type NoneType, which means the variable has no value or is empty.

For example, suppose you have a function that returns a tuple of values, but the function returns None instead of a tuple. If you try to unpack the returned value into variables, you will get this error.

To fix this error, you need to ensure that the variable you are trying to unpack is not None. You can do this by adding a condition to check if the variable is None before trying to unpack it.

For example:

result = my_function()
if result is not None:
    a, b, c = result
else:
    # handle the case where the function returned None

In this code, we first check if the result is not None before trying to unpack it into variables a, b, and c. If the result is None, we can handle the case accordingly.

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。
