huibai() missing 1 required positional argument: 'self'

This error message suggests that the `huibai` function is defined as an instance method within a class, and is missing the `self` parameter in its definition.

Instance methods in Python classes always require a reference to the instance itself as the first parameter, conventionally named `self`. This is used to access and modify the instance's attributes and behavior.

To fix this error, you need to add the `self` parameter to the `huibai()` function definition, like this:

class MyClass:
    def huibai(self, arg1, arg2):
        # method body here

Or, if `huibai()` is not intended to be an instance method and should be defined outside of any class, simply remove the `self` parameter from its definition:

def huibai(arg1, arg2):
    # function body here
