Generator and iterator in python, python generator Generator
I personally think that iterator and yield implement the same functions, but iterator must be implemented in the class, and yield is implemented in the real function, both of which will save the status.
The generator is also implemented by the iterator.

Python iterator and Generator
Let's talk about the iterator. It is convenient to use for loop traversal for container objects such as string, list, dict, and tuple. In the background, the for statement calls the iter () function on the container object. iter () is a python built-in function. Iter () returns an
Generator function: If the yield keyword appears in the function, then this function is the generator function, and yield is the function of generating a generator, and the generator function returns a generator.A generator is created by implementing a

1. iterator
An iterator is a way to access collection elements. The iterator object is accessed from the first element of the set until all elements are accessed. The iterator can only move forward, but this is nothing because people seldom step back on the iteration. In addition, the major advantage of the iterator is that it is not required to p

An iterator is a way to access collection elements. It has the following features:
1) Each call to the _ next _ () method only accesses one element and cannot be used back. This facilitates large data sets and saves memory; (When no element is accessible in the container, the next () method will throw a StopIteration e
