 Generator (computer science) - Wikipedia, the free encyclopedia
In computer science, a generator is a special routine that can be used to control the iteration behaviour of a loop.
The first time that a generator invocation is reached in a loop, an iterator object is created that encapsulates the state of the generator routine at its beginning, with arguments bound to the corresponding parameters.
The generator's body is then executed in the context of that iterator until a special yield action is encountered; at that time, the value provided with the yield action is used as the value of the invocation expression.

Generated code calls application code at lower levels of abstraction to manage the details of reading and writing the bytes in the instruction stream, which is the Toolkit's model of binary representation.
The encoder generator uses an equation solver [cite ramsey:solver] to compute the binary representation as a function of an abstraction.
A program generator needs to walk intermediate trees both in ways that are unaware of the semantics of particular operators (e.g., to find free variables) and in ways that are aware of the semantics of particular operators (e.g., to perform algebraic simplification).

 Python Generator Tricks LG #100
A generator is, simply put, a function which can stop whatever it is doing at an arbitrary point in its body, return a value back to the caller, and, later on, resume from the point it had `frozen' and merrily proceed as if nothing had happened.
This is one of the implications of using the yield statement in the body of the function.
from __future__ import generators def abc(): a = deff() for i in a: yield i yield 'abc' def deff(): a = ijk() for i in a: yield i yield 'deff' def ijk(): for i in (1,2,3): yield i yield 'ijk'

Indeed, there isn't a single field of science attached to pseudo-random generators, and this document originality might be to shed light on this topic from various angles in a single communication.
The generator is exercised by steps, and two things occur concurrently during each step: there is a transformation of the state information, and the generator outputs a fixed size bit string.
The truly random generators: electronic circuits that employ measurements of a natural phenomenon to provide totally unpredictable draws, contrary to pseudo-random number generators with their deterministic output sequence ([13]).

Called lavarand, the random-number generator is the tongue-in-cheek work of Robert G. Mende Jr., Landon Curt Noll, and Sanjeev Sisodiya of Silicon Graphics in Mountain View, Calif. (see http://lavarand.sgi.com/).
Random numbers are an immensely valuable commodity, not only for the operation of computer-based slot machines but also for computer simulations and for generating the secret strings of digits required to encode and decode sensitive information in cryptographic systems.
The computer simply follows a set procedure, and restarting the process with the same initial number, or seed value, produces exactly the same sequence of digits.

For example, you could place a piece of radioactive material in front of a Geiger counter and connect the Geiger counter to a computer.
So if you give the rand() function shown above the seed of 10 on one computer and look at the stream of numbers it produces, it will be identical to the stream of numbers produced on any computer that runs it with a seed of 10.
