(EXPRRESSION for VAR in ITERABLE if CONDITION) The logic of using a filtered generator expression can be described as: When the generator expression is evaluated, Python system will create a generator iterator, which wraps the generator function body inside the iterator. This iterator is then ...

The next function gives us the next item in a generator:>>> numbers = [2, 1, 3, 4, 7, 11, 18] >>> squares = (n**2 for n in numbers) >>> next(squares) 4 Generators keep track of the expression they need to evaluate on the iterable they're looping over and they keep ...
