'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. Note that this function must import all *packages* (NOT all modules!) on the given path, in order to access the __path__ attribute to find submodules. 'onerror' is a function which gets called with one argument (the name of the package which was being imported) if any exception occurs while trying to import a package. If no onerror function is supplied, ImportErrors are caught and ignored, while all other exceptions are propagated, terminating the search. Examples: # list all modules python can access walk_packages() # list all submodules of ctypes walk_packages(ctypes.__path__, ctypes.__name__+'.') cSs||krtSt||((s5J:\tools\MySQL Workbench 5.2 CE\python\lib\pkgutil.pyRˆs  "    cCsr|tjkrtj|}nt|tƒrb|}t|ddƒ}|dk rV|S|j}n|}t|ƒS(sDGet a PEP 302 "loader" object for module_or_name If the module or package is accessible via the normal import mechanism, a wrapper around the relevant part of that machinery is returned.

Intended use is to place the following code in a package's __init__.py: 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 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).

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.
