Selecting non-column data from rows

Let’s say we want to attach some data which is not necessarily dependent on table data to an existing query. For example let’s say we want to add the same teacher information to a list of name and courses of all students who are enrolled in the Python course.

In this case, we can directly select a string/number/boolean for a particular named column, in place of an actual column data.
