statistics.mode()

statistics.mode(data)

Return the most common data point from discrete or nominal data. The mode (when it exists) is the most typical value, and is a robust measure of central location.

If data is empty, or if there is not exactly one most common value, StatisticsError is raised.

mode assumes discrete data, and returns a single value. This is the standard treatment of the mode as commonly taught in schools:

>>> mode([1, 1, 2, 3, 3, 3, 3, 4])
3

The mode is unique in that it is the only statistic which also applies to nominal (non-numeric) data:

>>> mode(["red", "blue", "blue", "red", "green", "red", "red"])
'red'
