We create a databricks notebook with a default language like SQL, SCALA or PYTHON and then we write codes in cells. This example gets the value of the notebook task parameter that has the programmatic name age. You can highlight code or SQL statements in a notebook cell and run only that selection. dbutils utilities are available in Python, R, and Scala notebooks. Per Databricks's documentation, this will work in a Python or Scala notebook, but you'll have to use the magic command %python at the beginning of the cell if you're using an R or SQL notebook. Calling dbutils inside of executors can produce unexpected results or potentially result in errors. Another candidate for these auxiliary notebooks are reusable classes, variables, and utility functions. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

For a list of available targets and versions, see the DBUtils API webpage on the Maven Repository website. Calling dbutils inside of executors can produce unexpected results or potentially result in errors. Similar to the dbutils.fs.mount command, but updates an existing mount point instead of creating a new one. Libraries installed by calling this command are available only to the current notebook. The Python notebook state is reset after running restartPython; the notebook loses all state including but not limited to local variables, imported libraries, and other ephemeral states.
