REMARKS

* No prefix required - Core
* Return a new array of bytes. The bytearray class is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Bytearray Operations.
* If "source" is a string, you must also give the encoding (and optionally, errors) parameters; bytearray() then converts the string to bytes using str.encode().
* If "source" is an integer, the array will have that size and will be initialized with null bytes.
* If "source" is an object conforming to the buffer interface, a read-only buffer of the object will be used to initialize the bytes array.
* If "source" is an iterable, it must be an iterable of integers in the range 0 <= x < 256, which are used as the initial contents of the array.
* Without an argument, an array of size 0 is created.
