SMTP.ehlo(name='') Identify yourself to an ESMTP server using EHLO. The hostname argument defaults to the fully qualified domain name of the local host. Examine the response for ESMTP option and store them for use by has_extn(). Also sets several informational attributes: the message returned by the server is stored as the ehlo_resp attribute, does_esmtp is set to true or false depending on whether the server supports ESMTP, and esmtp_features will be a dictionary containing the names of the

is_signed(x) Returns True if x is negative; otherwise returns False.

getpass.getuser() Return the “login name” of the user. This function checks the environment variables LOGNAME, USER, LNAME and USERNAME, in order, and returns the value of the first one which is set to a non-empty string. If none are set, the login name from the password database is returned on systems which support the pwd module, otherwise, an exception is raised.

socket.create_connection(address[, timeout[, source_address]]) Connect to a TCP service listening on the Internet address (a 2-tuple (host, port)), and return the socket object. This is a higher-level function than socket.connect(): if host is a non-numeric hostname, it will try to resolve it for both AF_INET and AF_INET6, and then try to connect to all possible addresses in turn until a connection succeeds. This makes it easy to write clients that are compatible to both IPv4 and IPv6. Passi

appendleft(x) Add x to the left side of the deque.

class xml.sax.saxutils.XMLFilterBase(base) This class is designed to sit between an XMLReader and the client application’s event handlers. By default, it does nothing but pass requests up to the reader and events on to the handlers unmodified, but subclasses can override specific methods to modify the event stream or the configuration requests as they pass through.

assert_has_calls(calls, any_order=False) assert the mock has been called with the specified calls. The mock_calls list is checked for the calls. If any_order is false (the default) then the calls must be sequential. There can be extra calls before or after the specified calls. If any_order is true then the calls can be in any order, but they must all appear in mock_calls. >>> mock = Mock(return_value=None) >>> mock(1) >>> mock(2) >>> mock(3) >>> m

Cookie.domain_initial_dot True if the domain explicitly specified by the server began with a dot ('.').

binascii.a2b_base64(string) Convert a block of base64 data back to binary and return the binary data. More than one line may be passed at a time.

class shelve.DbfilenameShelf(filename, flag='c', protocol=None, writeback=False) A subclass of Shelf which accepts a filename instead of a dict-like object. The underlying file will be opened using dbm.open(). By default, the file will be created and opened for both read and write. The optional flag parameter has the same interpretation as for the open() function. The optional protocol and writeback parameters have the same interpretation as for the Shelf class.
