+## Compare Character sequences
+
+SequenceMatcher is a class in difflib that can be used to compare the similarity between two sequences (such as strings).
+It uses the [Ratcliff/Obershelp](https://xlinux.nist.gov/dads/HTML/ratcliffObershelp.html) algorithm to calculate the similarity between two sequences.
