sum(iterable[, start]) Sums start and the items of an iterable from left to right and returns the total. start defaults to 0. The iterable‘s items are normally numbers, and the start value is not allowed to be a string. For some use cases, there are good alternatives to sum(). The preferred, fast way to concatenate a sequence of strings is by calling ''.join(sequence). To add floating point values with extended precision, see math.fsum(). To concatenate a series of iterables, consider using

window.get_wch([y, x]) Get a wide character. Return a character for most keys, or an integer for function keys, keypad keys, and other special keys. New in version 3.3.

timezone.tzname(dt) Return the fixed value specified when the timezone instance is constructed or a string ‘UTCsHH:MM’, where s is the sign of offset, HH and MM are two digits of offset.hours and offset.minutes respectively.

emit(record) Sends the record to the Web server as a URL-encoded dictionary. The mapLogRecord() method is used to convert the record to the dictionary to be sent.

importlib.machinery.DEBUG_BYTECODE_SUFFIXES A list of strings representing the file suffixes for non-optimized bytecode modules. New in version 3.3. Deprecated since version 3.5: Use BYTECODE_SUFFIXES instead.

random.lognormvariate(mu, sigma) Log normal distribution. If you take the natural logarithm of this distribution, you’ll get a normal distribution with mean mu and standard deviation sigma. mu can have any value, and sigma must be greater than zero.

start([initializer[, initargs]]) Start a subprocess to start the manager. If initializer is not None then the subprocess will call initializer(*initargs) when it starts.

devpoll.modify(fd[, eventmask]) This method does an unregister() followed by a register(). It is (a bit) more efficient that doing the same explicitly.

logging.disable(lvl) Provides an overriding level lvl for all loggers which takes precedence over the logger’s own level. When the need arises to temporarily throttle logging output down across the whole application, this function can be useful. Its effect is to disable all logging calls of severity lvl and below, so that if you call it with a value of INFO, then all INFO and DEBUG events would be discarded, whereas those of severity WARNING and above would be processed according to the logg

exception configparser.DuplicateOptionError Exception raised by strict parsers if a single option appears twice during reading from a single file, string or dictionary. This catches misspellings and case sensitivity-related errors, e.g. a dictionary may have two keys representing the same case-insensitive configuration key.
