Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

validator.expect_column_values_to_not_be_null(column="name")
validator.expect_column_values_to_be_between(
    column="age", min_value=0, max_value=100
)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

adapter = HTTPAdapter(max_retries=restries)

Any command-line input or output is written as follows:

databricks fs ls

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: “Here we have the main page for workflows; to create a new workflow, there is a Create job button at the top left.”
