Find x-th percentile of a sequence without numpy

Because sometimes you need one function only.

Install

pip install percentiles

Use

>>> import percentiles
>>> percentiles.percentile([100, 120, 130, 1000], 75)
347.5
>>> from numpy import percentile
>>> percentile([100, 120, 130, 1000], 75)
347.5
