It solves a common Python pattern that would otherwise require awkward constructs like next(filter(...)) or generator expressions with conditional logic.\n\nThe package provides a single function with three parameters: the iterable to search, an optional key function to customize how truthiness is evaluated (similar to how sorted() uses key), and an optional default to return when no true value is found. It has no dependencies and works across Python 2 and 3 implementations, making it a drop-in replacement for verbose iteration patterns, particularly useful in regex matching chains or filtering operations where readability matters.","worth_installing":"Yes. This is a stable, MIT-licensed utility with zero dependencies and low install friction. It solves a genuine readability problem in Python iteration patterns. Use it when you find yourself writing next(filter(...)) or generator comprehensions with conditionals\u2014first() is clearer and more Pythonic. The 2019 release date is not a concern given the code's simplicity and the active repository."},"id":"first","links":{"html":"https://skillfed.io/packages/first","md":"https://skillfed.io/packages/first.md","pypi":"https://pypi.org/project/first/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2019-03-07","license_spdx":null,"license_treatment":"permissive","name":"first","python_support":"unspecified","summary":"Return the first true value of an iterable."},"popularity":{"monthly_downloads":785098,"position":5069,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.2"}
