Generators allow you to encapsulate the functions which generate values without worrying about buffering. This is done by using the notion of lazy evaluation. It means that a generator function continues to yield values until it is called again with "for" or any other iterator. This is extremely useful in calculations. These generators can run on biodiesel and low-sulfur diesel fuel. Find the most value diesel gensets - click here or go to our marketplace to find out more information.
