When you create an object and then assign it to another variable, Python does not copy the object, but simply copies the object's reference.When you assign a value to an object (either as a parameter pass or as a return value), Python, like Java, always passes a reference to the original object, not a copy."" "passes a reference to the original object instead of

column with a unique constraint. A FOREIGN KEY constraint is called a composite foreign key if it is a primary key that points to multiple columns, and it itself has more than one column. The foreign key column can automatically update itself to correspond to the rows or columns it references. This is called cascading and is a function built on a relational database. Foreign keys can refer to their own tables. This is called the "self-citation" foreign key. We need to create a addresses table i

: Something is done by a secretary, and nothing is done by a secretary. What is a secretary? Because the boss is very lazy and very fat. Therefore, the boss is a person who is unwilling to take measures at will, and is unwilling to contact other things positively.
