In writing some Python code, I came upon a need for a string-like data structure that offers fast insertion into, access to, and deletion from arbitrary positions. The first data structure that came to mind was a rope. Does Python have a rope data structure already implemented somewhere? I've looked through the standard library and PyPI, but I haven't seen one. (It doesn't help that there's a refactoring library for Python by the name of Rope as well as a company called Python Rope that sells wire rope.)
They allow you to quickly access and manipulate the data. Python includes many built-in data structures for easy data management. In this article we will learn about one of Python's most important data structures: Strings.
In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used to efficiently store and manipulate a very long string.
A Rope data structure is a tree data structure which is used to store or manipulate large strings in a more efficient manner. It allows for operations like insertion, deletion, search and random access to be executed faster and much more efficiently in comparison to a traditional String.
A cord tree is a binary tree of strings. A node in this tree can be a leaf node or an internal node. An internal node has two children, a left child and a right child. It also has a length of all the children under it. A leaf nodes have a value and a length.
There isn't one in the standard library, but there are implementations out there, e.g. pyropes
.
There's also this list of various non-built-in data structure implementations for Python.
Yes! there is one package available at PyPI.org for Rope data structure(named pyropes), written purely in Python 3. You can install it using
pip install pyropes
It also have full documentation on how to use it. Though it requires Python >=3.6(because it uses f-strings)
