Because the name isn't an object, "load method" falls back to load attribute via a slow internal path. Importing the desired function directly is 10-15% faster: WebIterators are objects that can be iterated upon. They serve as a common feature of the Python programming language, neatly tucked away for looping and list comprehensions. Any object that can derive an iterator is known as an iterable. There is a lot of work that goes into constructing an iterator.

WebAn iterator is an object with a state. An iterator object remembers where it is during an iteration. Iterators also know how to get the next value in the collection. They do this by using the __next__() method, which by the way is a method every iterator needs to have. Let’s continue with the numbers list example and grab the iterator of the ...
