Hands-On Regular Expressions in Python
summary
A hands‑on walkthrough uses Python’s re module to show wholegood details: re.search/re.sub and re.findall/re.finditer behavior, raw strings r'...', anchors, character classes, quantifiers, and the distinction between match objects and booleans. Demonstrations use flags=re.IGNORECASE and re.VERBOSE to make patterns case‑insensitive and readable, and show capturing versus non‑capturing groups plus alternation with |. Exercises run from exercises.zip and test.py on python3 and the test framework verifies patterns and substitutions as shown.
