email.utils.parsedate_to_datetime(date) The inverse of format_datetime(). Performs the same function as parsedate(), but on success returns a datetime. If the input date has a timezone of -0000, the datetime will be a naive datetime, and if the date is conforming to the RFCs it will represent a time in UTC but with no indication of the actual source timezone of the message the date comes from. If the input date has any other valid timezone offset, the datetime will be an aware datetime with

time.hour In range(24).

exception smtplib.SMTPServerDisconnected This exception is raised when the server unexpectedly disconnects, or when an attempt is made to use the SMTP instance before connecting it to a server.

emit(record) The record is formatted, and then sent to the syslog server. If exception information is present, it is not sent to the server. Changed in version 3.2.1: (See: issue 12168.) In earlier versions, the message sent to the syslog daemons was always terminated with a NUL byte, because early versions of these daemons expected a NUL terminated message - even though it’s not in the relevant specification (RFC 5424). More recent versions of these daemons don’t expect the NUL byte but st

somenamedtuple._asdict() Return a new OrderedDict which maps field names to their corresponding values: >>> p = Point(x=11, y=22) >>> p._asdict() OrderedDict([('x', 11), ('y', 22)]) Changed in version 3.1: Returns an OrderedDict instead of a regular dict.

operator.__floordiv__(a, b) Return a // b.

class difflib.SequenceMatcher This is a flexible class for comparing pairs of sequences of any type, so long as the sequence elements are hashable. The basic algorithm predates, and is a little fancier than, an algorithm published in the late 1980’s by Ratcliff and Obershelp under the hyperbolic name “gestalt pattern matching.” The idea is to find the longest contiguous matching subsequence that contains no “junk” elements; these “junk” elements are ones that are uninteresting in some sense,

class csv.unix_dialect The unix_dialect class defines the usual properties of a CSV file generated on UNIX systems, i.e. using '\n' as line terminator and quoting all fields. It is registered with the dialect name 'unix'. New in version 3.2.

abstractmethod unregister(fileobj) Unregister a file object from selection, removing it from monitoring. A file object shall be unregistered prior to being closed. fileobj must be a file object previously registered. This returns the associated SelectorKey instance, or raises a KeyError if fileobj is not registered. It will raise ValueError if fileobj is invalid (e.g. it has no fileno() method or its fileno() method has an invalid return value).

operator.ixor(a, b) operator.__ixor__(a, b) a = ixor(a, b) is equivalent to a ^= b.
