WebImplementation Details¶. The Sorted Containers internal implementation is based on a couple observations. The first is that Python’s list is fast, really fast.Lists have great characteristics for memory management and random access. The second is that bisect.insort is fast. This is somewhat counter-intuitive since it involves shifting a series … WebBisect Algorithm enables us to keep the list in sorted order after inserting each data element. This is necessary as this reduces the overhead time required to sort the list repeatedly after inserting each data element. Python, in its definition, offers the bisect algorithms with the help of the bisect module.
