In this paper, we summarize the common operation methods of the list in Python for reference. Here's how:
First, Python creates a list:
Sample_list = [' A ', 1, (' A ', ' B ')]
Second, Python list operation:
Assume the following table:
Sample_list
This example describes how Python implements an infinite list of elements, which can be accomplished using yield.
The 2-segment instance code described below implements a simple list of infinite elements through the Python Yield generator.

This example shows the number of occurrences of duplicates in the Python statistics list, and is a useful feature for beginners in Python to learn from. Here's how:
For a list, such as [1,2,2,2,2,3,3,3,4,4,4,4], now we need to count the duplicates
In Python, you can define a property as a private property by adding a double underscore to the property variable name, such as an example:

In general, a function is a well-organized, reusable piece of code that has some functionality. Functions can improve the modularity of the application and the reuse of the code, and in Python there are many built-in functions, such as print (), and
The following code is directly retained, convenient for later access to reuse.
