WebMay 11, 2024 · Video. Sorted Containers is an Apache2 licensed sorted collections library, written in pure-Python, and fast as C-extensions. It was created by Grant Jenks and is an open source library. It is a collection of containers that allow us to insert and remove elements very efficiently while maintaining sorted order. 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.
