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: “Similarly, the MAX, MIN, COUNT, and AVERAGE functions are used to obtain the maximum, minimum, count, and average values, respectively.”

A block of code is set as follows:

SUMX TEST = SUMX (
    Products,
    Products[Price] * Products[Qty]
    )

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

Dates Between =
    CALCULATE (
        [SUM Total Sales],
        DATESBETWEEN (
            'Calendar'[Date],
            "01-01-2008", "31-03-2008"
        )
    )

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

pip install numpy

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “To do this, go to File | Options and Settings | Options and open the Preview features menu.”
