shelve.open(filename, flag='c', protocol=None, writeback=False) Open a persistent dictionary. The filename specified is the base filename for the underlying database. As a side-effect, an extension may be added to the filename and more than one file may be created. By default, the underlying database file is opened for reading and writing. The optional flag parameter has the same interpretation as the flag parameter of dbm.open(). By default, version 3 pickles are used to serialize values. T

__iter__() values() Return an iterator over representations of all messages if called as itervalues() or __iter__() or return a list of such representations if called as values().

get_info() Return a string containing the “info” for a message. This is useful for accessing and modifying “info” that is experimental (i.e., not a list of flags).

from_buffer_copy(source[, offset]) This method creates a ctypes instance, copying the buffer from the source object buffer which must be readable. The optional offset parameter specifies an offset into the source buffer in bytes; the default is zero. If the source buffer is not large enough a ValueError is raised.
