Get your resources faster, with importlib.resources
summary
importlib.resources provides concrete APIs like read_binary, read_text and context-manager path that avoid pkg_resources import-time overhead, work with zipimport, and require resources to live inside real packages. LinkedIn reports 25–50% faster CLI responsiveness after switching (with Shiv replacing PEX). Backported shim lets older Pythons adopt the efficient behavior. The library builds on Python’s import system, creates temporary files only inside a with block, and exposes loader hooks for custom sources.
