It exposes this core capability through functions like `varname()` (to get the assignment variable name), `argname()` (to fetch the names or source of arguments passed to a function), and `will()` (to detect the next attribute access). The library depends on executing for bytecode inspection and typing-extensions for type hints.\n\nThe package is useful when you need runtime introspection of variable names\u2014for instance, to automatically populate an object's `__varname__` attribute with the name it was assigned to, to create dictionaries without explicitly repeating key names, or to implement debugging utilities that print variable names alongside their values. It handles complex cases like multiple assignment, nested unpacking, and calls wrapped through intermediate functions.","worth_installing":"Yes. The package is actively maintained, has low install friction, carries a permissive MIT license, and solves a real metaprogramming need. It is well-documented with concrete examples. Install it if you need runtime variable name introspection; skip it if your code does not require that capability."},"id":"varname","links":{"html":"https://skillfed.io/packages/varname","md":"https://skillfed.io/packages/varname.md","pypi":"https://pypi.org/project/varname/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-16","license_spdx":null,"license_treatment":"permissive","name":"varname","python_support":"supports_current","summary":"Dark magics about variable names in python."},"popularity":{"monthly_downloads":414920,"position":6828,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.0.0"}
