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.

Advanced Usage Analysis of the iterator and generator in Python, python Generator
Iterator
An iterator is an object attached to the iteration protocol. It basically means that it has a next method. When called, it returns the next item in the sequence. When no project can be returned, A (raise) StopIteration exception is thrown.
The iteration object allows a loop. It retains the state (location) of a single
tool, even if it provides an infinite number of primes is completely feasible, because it provides only one prime each time, there is no memory exhaustion problem. So, does this tool exist? Of course there is, and the name is called Generator (generator).2, Generator (Generator) Principle Introduction: There is a keyw
With a deep understanding of the Python Generator (Generator), we can simply create a list using the list generation method, but the list capacity is limited due to memory restrictions. In addition, creating a list containing 1 million elements not only occupies a large storage space, but if we only need to access the first few elements, the space occupied by the vast majority of elements is wasted.

This article mainly introduces the details of the Python Generator (Generator). This article describes what generators are, simple generators, generators with yield statements, and enhanced generators, for more information, see generate a list. However, due to memory restrictions, the list capacity must be limited. In addition, creating a list containing 1 million elements not only occupies a large storage
This is a series of articles, starting from the basics, and introducing the generator in Python and coroutine (mainly about Coroutine), and detailing the various advanced uses of coroutine in Python, Finally, a simple multi-tasking operating system is implemented with Coroutine.Actually also read this article the study note!

Python generator and yield, Python generator yieldList derivation and generator expression
When we create a list, we create an object that can be iterated:
>>> squares=[n*n for n in range(3)]>>> for i in squares:print i014
This kind of list creation operation is very common, called list derivation. However, the list iterators, such as str and file, are easy to us
Python generator summary, python generator Summary
Generator concept:The generator does not save the results in a series, but stores the results in the generator state. A value is returned each time the iteration is performed until the StopIteration exception ends.A
Lightweight "set" iterator-Generator, set-generator
Generator is a new language feature added to PHP 5.5. However, it does not seem to be widely used by many PHP developers. Therefore, before learning about the improvements made by PHP 7 to Generator, let's take a simple but obvious example to understand what problems
Python-Generator/point you don't know, python-generator1. What is a generator?
By using the list generation method, we can directly create a list. However, due to memory restrictions, the list capacity must be limited. In addition, creating a list containing 1 million elements not only occupies a large storage space, but if we only need to access the first few elements, the space occupied by the vast majori

Everything starts with Iterator and GeneratorTo make it easier for new start-up developers to understand, half of this article is about iterator interfaces (Iterator) and Generator classes, which are understood to be skipped directly.It is necessary to know iterations and iterators before you understand most of the concepts in this article. In fact, the iteration knows what it is, but I don't know (re

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
