How do I create a generator function

generator function, Python, yield, iterator, lazy evaluation, Python generators, memory efficiency

A generator function in Python allows you to declare a function that behaves like an iterator. It uses the `yield` statement to produce a series of values lazily, making it memory efficient.


        def my_generator():
            for i in range(5):
                yield i * 2
                
        gen = my_generator()
        for value in gen:
            print(value)  # This will print 0, 2, 4, 6, 8
