By default, pip uses ``importlib.metadata`` on Python 3.11+, and ``pkg_resources`` otherwise. This can be overridden by a couple of ways: * If environment variable ``_PIP_USE_IMPORTLIB_METADATA`` is set, it dictates whether ``importlib.metadata`` is used, regardless of Python version. * On Python 3.11+, Python distributors can patch ``importlib.metadata`` to add a global constant ``_PIP_USE_IMPORTLIB_METADATA = False``. This makes pip use ``pkg_resources`` (unless the user set the aforementioned environment variable to *True*). _PIP_USE_IMPORTLIB_METADATAN) FrT) contextlibsuppressKeyError ValueErrorboolrosenvironsys version_infoimportlib.metadatagetattrmetadata importlibr&R/var/www/html/venv/lib/python3.10/site-packages/pip/_internal/metadata/__init__.py_should_use_importlib_metadatas r(c@s.eZdZUded<eeed<eeed<dS)Backendz%Literal["importlib", "pkg_resources"]NAME Distribution EnvironmentN)__name__ __module__ __qualname____annotations__rr r r&r&r&r'r)4s  r))maxsizecCs2trddlm}tt|Sddlm}tt|S)Nrr$) pkg_resources)r(r%rr)r2)r%r2r&r&r'r:s     rcCs tjS)aGet the default representation for the current environment.
