'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__+'.') c S s | |v rdS d|| <
