listen(backlog) Listen for connections made to the socket. The backlog argument specifies the maximum number of queued connections and should be at least 1; the maximum value is system-dependent (usually 5).

class io.TextIOBase Base class for text streams. This class provides a character and line based interface to stream I/O. There is no readinto() method because Python’s character strings are immutable. It inherits IOBase. There is no public constructor. TextIOBase provides or overrides these data attributes and methods in addition to those from IOBase: encoding The name of the encoding used to decode the stream’s bytes into strings, and to encode strings into bytes. errors The error

email.iterators.body_line_iterator(msg, decode=False) This iterates over all the payloads in all the subparts of msg, returning the string payloads line-by-line. It skips over all the subpart headers, and it skips over any subpart with a payload that isn’t a Python string. This is somewhat equivalent to reading the flat text representation of the message from a file using readline(), skipping over all the intervening headers. Optional decode is passed through to Message.get_payload.

logging.addLevelName(lvl, levelName) Associates level lvl with text levelName in an internal dictionary, which is used to map numeric levels to a textual representation, for example when a Formatter formats a message. This function can also be used to define your own levels. The only constraints are that all levels used must be registered using this function, levels should be positive integers and they should increase in increasing order of severity. Note If you are thinking of defining you

csvreader.dialect A read-only description of the dialect in use by the parser.

ac_out_buffer_size The asynchronous output buffer size (default 4096).

json.loads(s, encoding=None, cls=None, object_hook=None, parse_float=None, parse_int=None, parse_constant=None, object_pairs_hook=None, **kw) Deserialize s (a str instance containing a JSON document) to a Python object using this conversion table. The other arguments have the same meaning as in load(), except encoding which is ignored and deprecated. If the data being deserialized is not a valid JSON document, a JSONDecodeError will be raised.

reverse() Reverse the elements of the deque in-place and then return None. New in version 3.2.

curses.napms(ms) Sleep for ms milliseconds.
