By default, pip uses ``importlib.metadata`` on Python 3.11+, and ``pkg_resources`` otherwise. Up to Python 3.13, 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, for Python <3.14. * On Python 3.11, 3.12 and 3.13, 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*). On Python 3.14+, the ``pkg_resources`` backend cannot be used. )T_PIP_USE_IMPORTLIB_METADATANr Fr) sys version_info contextlibsuppressKeyError ValueErrorboolr osenvironimportlib.metadatagetattrmetadata importlibr(Q/var/www/shaz/venv/lib/python3.9/site-packages/pip/_internal/metadata/__init__.py_should_use_importlib_metadatas 0 r*cCs:tjdkrdSddl}t|jdr&dStddddddS) Nrrrz7Using the pkg_resources metadata backend is deprecated.zpto use the default importlib.metadata backend, by unsetting the _PIP_USE_IMPORTLIB_METADATA environment variablez26.3i4)reason replacementgone_inissue)rrr#hasattrr%rr&r(r(r))_emit_pkg_resources_deprecation_if_needed:s  r0c@s.eZdZUded<eeed<eeed<dS)Backendz%Literal["importlib", "pkg_resources"]NAME Distribution EnvironmentN)__name__ __module__ __qualname____annotations__rr r r(r(r(r)r1Ss  r1)maxsizecCs8trddlm}tt|Stddlm}tt|S)Nr r&) pkg_resources)r*r'rr1r0r:)r'r:r(r(r)rYs    rcCs tjS)aGet the default representation for the current environment.
