I am an infrequent user of this package and this function. My two cents:
* Leave the current behavior as-is.
* Continue to throw an exception for no data.
* Add an argument, named perhaps mutli=False, that if set to True causes
the function to a return a list of modes, including if there is only a
single mode. statistics.mode((1, 2, 2, 3, 3, 4, 4, 5), multi=True) would
return [2, 3, 4].
* Would still throw StatisticsError if no data or if every element occurs
exactly the same number of times (for example,
statistics.mode(range(1000000000), multi=True))
I think that it would be better to have a separate function instead of
having the function sometimes return a single value and sometimes a list
of values.
There's an interesting answer here:
