New in version 2.3.
This module provides a single function:
| path, name) |
from pkgutil import extend_path __path__ = extend_path(__path__, __name__)
This will add to the package's __path__ all subdirectories of
directories on sys.path named after the package. 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 checking for duplicates, all entries found in a
*.pkg file are added to the path, regardless of whether they
exist 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 (Unicode or 8-bit) 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).
