Python iterator and GeneratorYou can also implement an iterator by yourself. As mentioned above, you only need to return an object in the _ iter _ method of the class. This object has a next () method, this method can throw a StopIteration exception when appropriate. However, there is not much time to implement the iterator by yourself. It is easier to use the generator even if needed. #! /Usr/bin/env python # coding = UTF-8 class test: def _ init _ (

Learning python following Liaoche's blog, and seeing the generator chapter, first mentions Generator, yield, and then in the search for information, and found the concept of the co-process, this article summarizes these concepts. 　　generator , literally, is the generator, which is implemented in two ways: 1, is differ

Python Study Notes 2: Build sequence: List derivation and generator expression, python Study NotesWelcome to my website: www. comingnext. cn1. about Python built-in Sequence Types A. differentiate container Sequences Based on whether different types of data can be stored: The list, tuple, and collections. deque sequences can store different types of data.Flat sequence: Str, bytes, bytearray, memoryview, and array. array can only accommodate one type.

　　The main content of this update:　　1. Increase the view of Oracle table creation statement.2. Added support for MySQL code generation.3, the comprehensive reconstruction of multi-threaded support, change the past will not cause the phenomenon of exit without reason.The Rdiframework.net code generator V3.1 version modifies the framework portion of the 3.0 version to make a lot of adjustments, adds support for the MYSQL database, supports generating UI

GeneratorJust having the ability to generate something, if not __next__ used, is not worth the Gain. Create a generator function>>> def scq (): ... print ("11") # when the yield keyword is encountered in a function code block, This function is a generator function ... yield 1 ...Print ("+") ... yield 2 ... Print ("+") ... yield 3 ...Assign the generator to

MyBatis can be understood as a semi-automated ORM Framework, through annotations or configuration XML mapping files to handwritten related SQL statements, and not as I introduced the ORM of the article as a whole object operation database additions and deletions. In fact, you will find that handwriting configuration XML mapping file is a very painful thing, because of this, MyBatis provides a generator tool, only need to configure the database connect

Understand:We first use a popular analogy to understand the next generator, to the restaurant to eat, we ordered the menu, the chef is not a one-time dish are all up, but a dish. The chef here is a generator object. The builder is a Python feature, and Python uses the generator to support deferred operations, producing results only when they are good, rather than

One: What is an iterator protocol1. The iterator protocol means that the object must provide a next method that either returns the next item in the iterator, or causes a Stoplteration exception to terminate the protocol (only backward cannot go forward)2. An iterative object: An object that implements an iterator protocol (how to: Define an _iter_ () method within an object)3. The Protocol is a convention that iterates over an object, implements an iterator protocol, and Python's internal tools

Based on the revision and source code analysis of mybatis-generator-core 1.3.5, mybatisgeneratorcoreProject Description Mybatis-generator is used to generate code files such as entity classes based on database tables and fields. During the National Day, I analyzed the mybatis-generator-core source code and wrote quite detailed Chinese comments. Let's take a look.
