Python generators

Python generator expressions offer a succinct and efficient way of creating simple generators. Generator expression syntax is similar to that of list comprehensions. And much like those, generator expressions allow you to generate sequences by applying expressions to items in an iterable and potentially filtering them based on specified conditions.

Python generators allow you to easily create efficient sequences of values using iterators. They can be implemented with special functions called generator functions, which use the yield keyword to yield values one at a time, rather than returning them all at once. Generators can also be created with generator expressions, which are similar to list comprehensions but produce values lazily as well.
