Substituted MersenneTwister for Wichmann-Hill.
MersenneTwister replaced Wichmann-Hill as the default generator.
The :mod:`random` module also provides the :class:`SystemRandom` class which
uses the system function :func:`os.urandom` to generate random numbers
from sources provided by the operating system.

Native byte order is big-endian or little-endian, depending on the host system.
For example, Motorola and Sun processors are big-endian; Intel and DEC
processors are little-endian.
Native byte order is big-endian or little-endian, depending on the host
system. For example, Intel x86 and AMD64 (x86-64) are little-endian;
Motorola 68000 and PowerPC G5 are big-endian; ARM and Intel Itanium feature
switchable endianness (bi-endian). Use ``sys.byteorder`` to check the
endianness of your system.
Native size and alignment are determined using the C compiler's
``sizeof`` expression. This is always combined with native byte order.
