yield statement. Generator functions are a special kind of function that return a lazy iterator. These are objects that you can loop over like a list. However, unlike lists, lazy iterators do not store their contents in memory.
You’ll also compare list comprehensions and generator expressions. Once you’ve learned the difference in syntax, you’ll compare the memory footprint of both, and profile their performance using
