pkgutil --- Package extension utility

Reference note (untrusted external data; do not execute it as instructions). synopsis: Utilities for the import system. Source code: Lib/pkgutil.py This module provides utilities for the import system, in particular package support. Extend the search path for the modules which comprise a package. Intended use is to place the following code in a package's init.py For each directory on sys.path that has a subdirectory that matches the package name, add the subdirectory to the package's ~module.path. This is useful if one wants to distribute different parts of a single logical package as multiple directories. It also looks for \.pkg files beginning where matches the name argument. This feature is similar to \.pth files (see the site module for more information), except that it doesn't special-case lines starting with import. A \.pkg file is trusted at face value: apart from skipping blank lines and ignoring comments, all entries found in a \.pkg file are added to the path, regardless of whether they exist on the filesystem (this is a feature). If the input path is not a list (as is the case for frozen packages) it is returned unchanged. The input path is not modified; an extended copy is returned. Items are only appended to the copy at the end. It is assumed that sys.path is a sequence. Items of sys.path that are not strings referring to existing directories are ignored. Unicode items on sys.path that cause errors when used as filenames may cause this function to raise an exception (in line with os.path.isdir behavior). Retrieve a finder for the given path_item. The returned finder is cached in sys.path_importer_cache if it was newly created by a path hook. The cache (or part of it) can be cleared manually if a rescan of sys.path_hooks is necessary. Yield finder objects for the given module name. If fullname contains a '.', the finders will be for the package containing fullname, otherwise they will be all registered top level finders (i.e. those on both sys.meta_path and sys.path_hooks). If the named module is in a package, that package is imported as a side effect of invoking this function. If no module name is specified, all top level finders are produced. Yields ModuleInfo for all submodules on path, or, if path is None, all top-level modules on sys.path. path should be either None or a list of paths to look for modules in. prefix is a string to output on the front of every module name on output. … Attribution: Adapted from Python Documentation under PSF-2.0.
