audioop.ratecv(fragment, width, nchannels, inrate, outrate, state[, weightA[, weightB]]) Convert the frame rate of the input fragment. state is a tuple containing the state of the converter. The converter returns a tuple (newfragment, newstate), and newstate should be passed to the next call of ratecv(). The initial call should pass None as the state. The weightA and weightB arguments are parameters for a simple digital filter and default to 1 and 0 respectively.

exception asyncio.QueueEmpty Exception raised when the get_nowait() method is called on a Queue object which is empty.

turtle.lt(angle) Parameters: angle – a number (integer or float) Turn turtle left by angle units. (Units are by default degrees, but can be set via the degrees() and radians() functions.) Angle orientation depends on the turtle mode, see mode(). >>> turtle.heading() 22.0 >>> turtle.left(45) >>> turtle.heading() 67.0

archive The file name of the importer’s associated ZIP file, without a possible subpath.

intersection_update(other, ...) set &= other & ... Update the set, keeping only elements found in it and all others.

read(size=-1) Read up to size bytes from the object and return them. As a convenience, if size is unspecified or -1, readall() is called. Otherwise, only one system call is ever made. Fewer than size bytes may be returned if the operating system call returns fewer than size bytes. If 0 bytes are returned, and size was not 0, this indicates end of file. If the object is in non-blocking mode and no bytes are available, None is returned.

tzinfo.fromutc(dt) This is called from the default datetime.astimezone() implementation. When called from that, dt.tzinfo is self, and dt‘s date and time data are to be viewed as expressing a UTC time. The purpose of fromutc() is to adjust the date and time data, returning an equivalent datetime in self‘s local time. Most tzinfo subclasses should be able to inherit the default fromutc() implementation without problems. It’s strong enough to handle fixed-offset time zones, and time zones acco

logb(context=None) For a nonzero number, return the adjusted exponent of its operand as a Decimal instance. If the operand is a zero then Decimal('-Infinity') is returned and the DivisionByZero flag is raised. If the operand is an infinity then Decimal('Infinity') is returned.
