What is a "notebook-scoped variable" in Databricks?

A "notebook-scoped variable" in Databricks is a variable that is accessible within a specific notebook. This means that the variable is defined and used only in the context of that particular notebook, allowing users to encapsulate their work without affecting or being affected by variables in other notebooks. The scope of these variables is limited to the notebook in which they are created, which helps prevent conflicts and unintended interactions between different parts of a project. By maintaining a confined scope, notebook-scoped variables facilitate a clean and organized environment for code execution and data manipulation. This concept is important for collaborating in shared environments where multiple users may be working with different notebooks simultaneously.
