I have an array ["agreement", "user", "client"]. Is there any way to convert its items into objects @agreement, @user, @client?

String Into Variable Name in Python Using the vars() Function. Instead of using the locals() and the globals() function to convert a string to a variable name in python, we can also use the vars() function. The vars() function, when executed in the global scope, behaves just like the globals() function.
Instance variables can be declared at the class level before or after use. Access modifiers can be given for instance variables. The instance variables are visible for all methods, constructors, and block in the class. Normally, it is recommended to make these variables private (access level).
An instance variable is a variable which is declared in a class but outside of constructors, methods, or blocks. Instance variables are created when an object is instantiated, and are accessible to all the constructors, methods, or blocks in the class. Access modifiers can be given to the instance variable.
An object that is created using a class is said to be an instance of that class. We will sometimes say that the object belongs to the class. The variables that the object contains are called instance variables.
