A. Fuzzy matching in regex Python is a technique used to match patterns in text data that are similar or partially match the target pattern. Fuzzy matching allows for variations in spelling, punctuation, and spacing in the text data. In Python, fuzzy matching can be achieved by using regular expressions and string distance functions like Levenshtein distance, Jaro-Winkler distance, or fuzzywuzzy library. The fuzzywuzzy library provides a set of functions for fuzzy string matching and can be used to find the best match among a set of possible matches.
