The Python language does not directly support proprietary methods and requires the programmer to grasp the opportunity to modify the features externally. Make a method or feature private, and add a double underline to its name Class secretive:

Preface In the course of learning Python today, I found that Python did not switch this syntax. So I wanted to do it in Python. Body In this article, we simulate the use of the switch to the normal database additions and deletions to the operation

There is no switch syntax in Python, but it can be implemented as a field, with the following code:* * Note: **python can also be implemented with the IF statement, but less efficient, to pass multiple if judgments #!/usr/bin/python #coding:
