Introduction to the actual operation steps of the Python Scope

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.
