Intended use is to place the following code in a package's __init__.py: from pkgutil import extend_path __path__ = extend_path(__path__, __name__) For each directory on sys.path that has a subdirectory that matches the package name, add the subdirectory to the package's __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 site.py), 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 are 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 of sys.path that cause errors when used as filenames may cause this function to raise an exception (in line with os.path.isdir() behavior). z.pkgNr3rr  #z Can't open z: )rAlistrr7r8r/rrr;rBrrJrsubmodule_search_locationsr appendrPrWisfilerrstriprrTstderrwrite)r;r sname_pkgparent_package_ final_name search_pathdirrportionsrportionpkgfilerliners rrrsB dD ! ! v I 7D$(OOC$8$8!NAz +n5>KK.)

This is a wrapper round the PEP 302 loader get_data API. The package argument should be the name of a package, in standard module format (foo.bar). The resource argument should be in the form of a relative filename, using '/' as the path separator. The parent directory name '..' is not allowed, and nor is a rooted name (starting with a '/'). The function returns a binary string, which is the contents of the specified resource. For packages located in the filesystem, which have already been imported, this is the rough equivalent of d = os.path.dirname(sys.modules[package].__file__) data = open(os.path.join(d, resource), 'rb').read() If the package cannot be located or loaded, or it uses a PEP 302 loader which does not support get_data(), then None is returned.

It is expected that `name` will be a string in one of the following formats, where W is shorthand for a valid Python identifier and dot stands for a literal period in these pseudo-regexes: W(.W)* W(.W)*:(W(.W)*)? The first form is intended for backward compatibility only. It assumes that some part of the dotted name is a package, and the rest is an object somewhere within that package, possibly nested inside other objects. Because the place where the package stops and the object hierarchy starts can't be inferred by inspection, repeated attempts to import must be done with this form. In the second form, the caller makes the division point clear through the provision of a single colon: the dotted name to the left of the colon is a package to be imported, and the dotted name to the right is the object hierarchy within that package. Only one import is needed in this form. If it ends with the colon, then a module object is returned. The function will return an object (which might be a module), or raise one of the following exceptions: ValueError - if `name` isn't in a recognised format ImportError - if an import failed when it shouldn't have AttributeError - if a failure occurred when traversing the object hierarchy within the imported package to get to the desired object.
