AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

natsort provides natural sorting for strings containing numbers, ordering them by numeric value rather than lexicographic order—so '10' sorts after '9' instead of after '1'.

Installs with zero runtime dependencies and is distributed as a pure-Python wheel, making it friction-free. The project shows active maintenance with recent commits and is classified as Production/Stable.

Licensed under MIT (permissive), allowing unrestricted use, modification, and distribution in both open-source and proprietary projects with minimal obligations.

pip install natsort
from natsort import natsorted
a = ['2 ft 7 in', '1 ft 5 in', '10 ft 2 in']
result = natsorted(a)
print(result)  # ['1 ft 5 in', '2 ft 7 in', '10 ft 2 in']

Verdict: natsort is a mature, zero-dependency utility for natural sorting that solves a common problem elegantly. With active maintenance, no known vulnerabilities, permissive licensing, and top-1000 popularity, it is a safe and practical choice for any project needing human-friendly string sorting.

Needs verification

• Whether optional PyICU dependency improves locale-aware sorting enough to warrant installation for non-Windows users
• Performance characteristics on very large datasets compared to built-in sorted()
