An example Analysis of the working principle of Python iterative Protocol

This article mainly introduces the example analysis of the working principle of Python iterative protocol, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article.

Description

1. The built-in function next () is just a call to the object. Next () function, which is part of the "iterative protocol" and can be found on all iterators.

Example

> x=iter (range (5)) > next (x) 1 > next (x) 1 > next (x) 2 > > next (x) 3 > next (x) 4 > next (x) Traceback (most recent call last): File ", line 1, in StopIteration Thank you for reading this article carefully. I hope the article" example Analysis of the working principle of Python iterative Protocol "shared by the editor will be helpful to you. At the same time, I hope you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
