class ctypes.c_ubyte Represents the C unsigned char datatype, it interprets the value as small integer. The constructor accepts an optional integer initializer; no overflow checking is done.

SMTP.docmd(cmd, args='') Send a command cmd to the server. The optional argument args is simply concatenated to the command, separated by a space. This returns a 2-tuple composed of a numeric response code and the actual response line (multiline responses are joined into one long line.) In normal operation it should not be necessary to call this method explicitly. It is used to implement other methods and may be useful for testing private extensions. If the connection to the server is lost w

selection_add(items) Add items to the selection.

class poplib.POP3_SSL(host, port=POP3_SSL_PORT, keyfile=None, certfile=None, timeout=None, context=None) This is a subclass of POP3 that connects to the server over an SSL encrypted socket. If port is not specified, 995, the standard POP3-over-SSL port is used. timeout works as in the POP3 constructor. context is an optional ssl.SSLContext object which allows bundling SSL configuration options, certificates and private keys into a single (potentially long-lived) structure. Please read Securi

assertSetEqual(first, second, msg=None) Tests that two sets are equal. If not, an error message is constructed that lists the differences between the sets. This method is used by default when comparing sets or frozensets with assertEqual(). Fails if either of first or second does not have a set.difference() method. New in version 3.1.

os.sched_setaffinity(pid, mask) Restrict the process with PID pid (or the current process if zero) to a set of CPUs. mask is an iterable of integers representing the set of CPUs to which the process should be restricted.

exception getopt.error Alias for GetoptError; for backward compatibility.

exception email.errors.MessageError This is the base class for all exceptions that the email package can raise. It is derived from the standard Exception class and defines no additional methods.

shlex.read_token() Read a raw token. Ignore the pushback stack, and do not interpret source requests. (This is not ordinarily a useful entry point, and is documented here only for the sake of completeness.)

set_transport(transport) Set the transport.
