Error:

TypeError: list indices must be integers or slices, not str

error code block:

AA is a set of list and dict data

The function insert receives two parameters, * args, * * kwargs

I hope to pass the list AA to * args

But in the execution of the program, a title display error was reported

first of all, the basic concepts of * args and * kwargs:

For * args and * * kwargs, we can call them parameter groups in functions, but they are different

1: * functions of args: – – – receive n position parameters and convert them into tuple form

2: The function of * * kwargs is to receive n keyword parameters and convert them into dict form

3: The location parameter must precede the keyword parameter, that is, (* args, * * kwargs)
 

problem analysis:

A * sign before the parameter AA indicates that it is an assembled tuple, otherwise Python will think AA is a positional parameter

So the program can run as expected
