Function Details

[hide private]

acquire_lock()

Acquires the interpreter's import lock for the current thread. This lock should be used by import hooks to ensure thread-safety when importing modules. On platforms without threads, this function does nothing.

Returns: None

find_module(...)

find_module(name, [path]) -> (file, filename, (suffix, mode, type)) Search for a module. If path is omitted or None, search for a built-in, frozen or special module and continue search in sys.path. The module name cannot contain '.'; to search for a submodule of a package, pass the submodule name and the package's __path__.

load_module(...)

load_module(name, file, filename, (suffix, mode, type)) -> module Load a module, given information returned by find_module(). The module name must include the full package name, if any.

lock_held()

Return True if the import lock is currently held, else False. On platforms without threads, return False.

Returns: boolean

new_module(name)

Create a new module. Do not enter it in sys.modules. The module name must include the full package name, if any.

Returns: module

release_lock()

Release the interpreter's import lock. On platforms without threads, this function does nothing.

Returns: None
