Soft-deprecating re.match()
TL;DR
Python introduced soft deprecation in 2023, allowing APIs to remain usable while discouraging new code development. This approach maintains documentation and testing without issuing warnings or guaranteeing future removal.
✦ Why It Matters
Review your code for soft-deprecated APIs and consider transitioning to recommended alternatives.
Key Takeaways
- Use re.prefixmatch() for half-anchored string matches.
- Avoid using re.match() in new code to prevent confusion.
- Utilize re.search() for matches anywhere in a string.
- Employ re.fullmatch() for complete string matches.
How It Works
re.match() checks for a match only at the start of a string, while re.search() looks for matches anywhere. re.fullmatch() ensures the entire string matches the pattern. The introduction of re.prefixmatch() clarifies the intent of matching at the start without ambiguity.
