macvector steps to compare two sequences

It first finds the longest common subsequence between two sequences and then divides both sequences into left parts of both original sequences (left subsequences of original sequences) and right parts of both original sequences (right subsequences of original sequences) based on that common subsequence. It requires that all the elements of both sequences be hashable in order for them to work.

As a part of this tutorial, we'll be explaining with simple and easy-to-understand examples, how we can compare sequences of different types using difflib module.Īt the core of the difflib module is SequenceMatcher class which implements an algorithm responsible for comparing two sequences. The difflib module provides different classes and methods to perform a comparison of two sequences and generate a delta. Python provides us with a module named difflib which can compare sequences of any type for us so that we don't need to write complicated algorithms to find common subsequences between two sequences. The algorithm which does can be useful in various situations like comparing contents of the files, contents of a single string, etc. These subsequences can help us understand how much two sequences are similar and how much different. Many times a Python developer needs to compare two sequences (list of numbers, list of strings, list of characters, etc.) to find matching subsequences in between them.
