@ -30,10 +30,13 @@ The :mod:`linecache` module defines the following functions:
.. index:: triple: module; search; path
If a file named *filename* is not found, the function will look for it in the
module search path, ``sys.path``, after first checking for a :pep:`302`
``__loader__`` in *module_globals*, in case the module was imported from a
zipfile or other non-filesystem import source.
If a file named *filename* is not found, the function first checks
for a :pep:`302` ``__loader__`` in *module_globals*.
If there is such a loader and it defines a ``get_source`` method,
then that determines the source lines
(if ``get_source()`` returns ``None``, then ``''`` is returned).
Finally, if *filename* is a relative filename,
it is looked up relative to the entries in the module search path, ``sys.path``.
