WebMay 31, 2024 · It is 3x slower than bisect.bisect_right(). def my_bisect_right(a, num): ok = len(a) ng = -1 while abs(ok - ng) > 1: mid = (ok + ng) // 2 if a[mid] <= num: ng = mid else: ok = mid return ok I created a list of 10M integers and ran bisect_right() against it. The bisect.bisect_right() took 24.82 sec while my_bisect_right() took 76.30 sec. WebThe module is called bisect because it uses a basic bisection algorithm to do its work. The source code may be most useful as a working example of the algorithm (the boundary conditions are already right!). The following functions are provided: bisect.bisect_left (a, x, lo=0, hi=len(a)) Locate the insertion point for x in a to maintain sorted ...
