To test database connection here we use pre-installed MySQL connector and pass credentials into connect() function like host, username and password. But what happens if we want to change the implementation in the future? You can also create a set using a type constructor called set (). In this tutorial, we will create a Listbox, and read what user has selected from the list of items. TypeError: add() takes exactly one argument (2 given), {'ef', 'ad', 'bc', 'cd', 'ab'} The universe is composed of units (indivisible units) like atoms (or bytes).
