Python data structure

The data structure of Python is mainly divided into set (), list[], and dict{}. This article mainly records some of the techniques used in the use of these results or the differences in the usage of some of these functions.

1. function get () differs from SetDefault ():

The Get () method provides a default value (without setting the default to None) and does not add a key to the Dictionary object;

The SetDefault () method adds a key and sets the default value.

2. Add elements to these three types of data structures:

Dict with SetDefault ();

List with append ();

Set with Add ().
