Returns one of the following values: \code{None} if the file can't be
|
||
|
|
opened because it's unreadable or doesn't exist; the empty string
|
||
|
|
(\code{""}) if the file's format can't be guessed; or a string
|
||
|
|
containing the required module name, such as \code{"dbm"} or
|
||
|
|
\code{"gdbm"}.
