Answer 1

The problem was the name of the file which contained the code in Visual Studio code.

I try to "import mysql" and the name of the file which contains the main training code is mysql.py

After the change of name was done(mysql.py > mysqltest.py), the code begins to work. That means when you try to import something in your program, python first checks the folder of the programs and after that the PAHT of libraries.
