Python tip 26: atomic grouping
Until Python 3.10, you had to use alternatives like the third-party regex module (https://pypi.org/project/regex/) for possessive quantifiers and atomic grouping. The `re` module now supports these features from Python 3.11 version. Greedy and non-greedy quantifiers will backtrack to help the overall pattern to succeed. Atomic grouping helps you isolate a portion of the pattern from further backtracking.
