I have an array of datetime objects, and I would like to find which element in the array is the closest to a given date (e.g datetime.datetime(2014,12,16)
)
This post shows how to find the nearest date which is not before the given date. How can I alter this code so that it can return dates that are before a given date?
For example, if the array housed elements datetime.datetime(2014,12,10)
and datetime.datetime(2014,12,28)
, the former item should be returned because it is closest to datetime.datetime(2014,12,16)
in absolute value.
def nearest(items, pivot):
return min(items, key=lambda x: abs(x - pivot))
Note that this will work for numbers too.
