It detects unindexed parameters (which fail in Python 2.6), mismatched argument counts, unused parameters, and mixing of implicit and explicit indexing. The plugin integrates directly into Flake8's error reporting and can be controlled via standard Flake8 ignore flags.\n\nIt works by parsing format strings and their corresponding format() calls, checking whether the parameters referenced in the string actually exist in the call's arguments. It distinguishes between format strings (where format() is called), docstrings, and plain strings, issuing different error codes for each context. The plugin handles variable arguments gracefully by skipping checks that would be unreliable when *args or **kwargs are present.","worth_installing":"Yes, if you use Flake8 and want to catch format string errors statically. The plugin is lightweight, actively maintained, permissively licensed, and has no known vulnerabilities. Install it if format string correctness matters in your codebase; skip it only if you never use str.format() or already rely on type checking and runtime testing to catch these errors."},"id":"flake8-string-format","links":{"html":"https://skillfed.io/packages/flake8-string-format","md":"https://skillfed.io/packages/flake8-string-format.md","pypi":"https://pypi.org/project/flake8-string-format/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-09","license_spdx":"MIT","license_treatment":"permissive","name":"flake8-string-format","python_support":"supports_current","summary":"string format checker, plugin for flake8"},"popularity":{"monthly_downloads":170838,"position":10385,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.4.0"}
