set_data(path, data) Concrete implementation of importlib.abc.SourceLoader.set_data().

name The name of the module that this loader will handle.

class importlib.machinery.SourcelessFileLoader(fullname, path) A concrete implementation of importlib.abc.FileLoader which can import bytecode files (i.e. no source code files exist). Please note that direct use of bytecode files (and thus not source code files) inhibits your modules from being usable by all Python implementations or new versions of Python which change the bytecode format. New in version 3.3. name The name of the module the loader will handle. path The path to the

classmethod invalidate_caches() Calls importlib.abc.PathEntryFinder.invalidate_caches() on all finders stored in sys.path_importer_cache.

class importlib.machinery.SourceFileLoader(fullname, path) A concrete implementation of importlib.abc.SourceLoader by subclassing importlib.abc.FileLoader and providing some concrete implementations of other methods. New in version 3.3. name The name of the module that this loader will handle. path The path to the source file. is_package(fullname) Return true if path appears to be for a package. path_stats(path) Concrete implementation of importlib.abc.SourceLoader.pat

is_package(fullname) Return true if path appears to be for a package.

load_module(name=None) Concrete implementation of importlib.abc.Loader.load_module() where specifying the name of the module to load is optional.

classmethod find_module(fullname, path=None) A legacy wrapper around find_spec(). Deprecated since version 3.4: Use find_spec() instead.

classmethod find_spec(fullname, path=None, target=None) Class method that attempts to find a spec for the module specified by fullname on sys.path or, if defined, on path. For each path entry that is searched, sys.path_importer_cache is checked. If a non-false object is found then it is used as the path entry finder to look for the module being searched for. If no entry is found in sys.path_importer_cache, then sys.path_hooks is searched for a finder for the path entry and, if found, is stor

importlib.machinery.OPTIMIZED_BYTECODE_SUFFIXES A list of strings representing the file suffixes for optimized bytecode modules. New in version 3.3. Deprecated since version 3.5: Use BYTECODE_SUFFIXES instead.
