Are you interested in the Python scope? Is there a detailed introduction to the actual operation steps of the Python scope? If you are interested in its related applications, you can click the following article to have a better understanding of it, the following is a detailed description of the article.
Local, upper layer, module, built-in
The python editor determines the scope according to the location defined by the variable, and then searches for the variable in the local, upper, module, and built-in order.

Scope of nested Functions
Python function parameters:
1-position Parameter
2. Keyword Parameters
3 * parameters of locations where args is collected and therefore do not match (type: tuple)
4 ** parameters for collecting unmatched keywords (type: dict) by kargs)
Python defines functions and calls functions in this form to define parameters.
If a function is defined, * args and ** kargs are used to collect parameters.
If a function is called, * args and ** kargs are the process of unpacking parameters.
Python defines and calls functions in the order of 1, 2, 3, and 4.
