In tkinter, <> is an event type that is typically associated with a virtual event. It represents a user-defined event that can be triggered manually in the application code. This event type allows developers to create custom events and bind them to specific functions or actions within the GUI application. By using <> events, developers can extend the functionality of tkinter widgets and provide more customized user interactions in their applications.
