random.weibullvariate(alpha, beta) Weibull distribution. alpha is the scale parameter and beta is the shape parameter.

sys.setrecursionlimit(limit) Set the maximum depth of the Python interpreter stack to limit. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python. The highest possible limit is platform-dependent. A user may need to set the limit higher when they have a program that requires deep recursion and a platform that supports a higher limit. This should be done with care, because a too-high limit can lead to a crash. If the new limit is too low at the cu

NNTP.ihave(message_id, data) Send an IHAVE command. message_id is the id of the message to send to the server (enclosed in '<' and '>'). The data parameter and the return value are the same as for post().

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.

datetime.isoformat(sep='T') Return a string representing the date and time in ISO 8601 format, YYYY-MM-DDTHH:MM:SS.mmmmmm or, if microsecond is 0, YYYY-MM-DDTHH:MM:SS If utcoffset() does not return None, a 6-character string is appended, giving the UTC offset in (signed) hours and minutes: YYYY-MM-DDTHH:MM:SS.mmmmmm+HH:MM or, if microsecond is 0 YYYY-MM-DDTHH:MM:SS+HH:MM The optional argument sep (default 'T') is a one-character separator, placed between the date and time portions of the res

ErrorHandler.error(exception) Called when the parser encounters a recoverable error. If this method does not raise an exception, parsing may continue, but further document information should not be expected by the application. Allowing the parser to continue may allow additional errors to be discovered in the input document.

POP3.rset() Remove any deletion marks for the mailbox.

addCleanup(function, *args, **kwargs) Add a function to be called after tearDown() to cleanup resources used during the test. Functions will be called in reverse order to the order they are added (LIFO). They are called with any arguments and keyword arguments passed into addCleanup() when they are added. If setUp() fails, meaning that tearDown() is not called, then any cleanup functions added will still be called. New in version 3.1.

bytes.isdigit() bytearray.isdigit() Return true if all bytes in the sequence are ASCII decimal digits and the sequence is not empty, false otherwise. ASCII decimal digits are those byte values in the sequence b'0123456789'. For example: >>> b'1234'.isdigit() True >>> b'1.23'.isdigit() False

class logging.handlers.QueueHandler(queue) Returns a new instance of the QueueHandler class. The instance is initialized with the queue to send messages to. The queue can be any queue- like object; it’s used as-is by the enqueue() method, which needs to know how to send messages to it. emit(record) Enqueues the result of preparing the LogRecord. prepare(record) Prepares a record for queuing. The object returned by this method is enqueued. The base implementation formats the record t
