Hope that helps Use bisect. It's not the most beautiful API, but it's exactly what you need.
You'll want to use bisect.bisect, which returns exactly what you want.

will help you The most efficient way if the list is already sorted is to use binary search. Java has a built in binary search for collections you might be able to use:

code :

arraylist.add(Collections.binarySearch(arraylist, newString), newString)

Hope this helps I figured out what was happening.
The problem in the end was a conflict with the sorting I was using and how the timestampable (https://atmospherejs.com/zimme/collection-timestampable) package adds the createdAt field.

Find Item lower or equal to value in list

hop of those help? I have a sorted csv file with multiple columns and I want to return the value or the index of an item in column 1. This csv file has around 300.000 to 400.000 values so I'm trying to avoid any min function since it would propably take to long and I need the value in under a second. , This is assuming that you have a sorted list:

code :

def foo(the_list, value):
    index = bisect.bisect_left(the_list, value)
    return the_list[index] if the_list[index] == value or index == 0 else the_list[index-1]
