yield statement

Game writingCode, The code is usually a continuous event. The result will look like this:[It can implementProgramDelayed execution or continuous execution of each part in a period of time.] Private int state = 0; void Update () {If (State = 0) {

The generator function is the first available feature in python2.2. It is built in Version 2.3 to support this feature, and yield becomes a keyword, the generator is enhanced in later versions (for example, exception handling is added ). Similar

simulate zip and map with iterative tools======================================================================We already know how zip can be combined to iterate over objects and how map maps functions.>>> S1 = ' abc ' >>> S2 = ' xyz123 ' >>> list

1. FunctionsUse DEF statements to define functions:def add(x, y): return x + yA function body is a series of statements that are executed when a function is called. The method of calling a function is to add a parameter after the function name.

The simplest and all optimizations are best done with less effort. For example, when an enemy is far from the perfect time, it is acceptable for the enemy to fall asleep. Nothing was done until the player was near. This is a slow way to handle the

Python iterators and generatorsIteratorsIterators in Python provide the class sequence object (Sequence-like objects) with an interface to a class sequence that iterates not only over a Sequence object (string, list, tuple), but also on a sequence,

In Python (the Python environment in this article is python2.7), functions that use the yield keyword are called generator (generators). Therefore, in order to understand yield, we must first understand generator, and before we understand generator,

Introduction The WITH statement is a feature associated with exception handling that was introduced from Python 2.5 (the version 2.5 is to be imported through the From __future__ import with_statement), and defaults are available from version 2.6

Most of the time, we need to collect results based on certain conditions. For this reason, we need to create some set objects, insert and output them to these sets, and finally return the set. However, this is annoying. One simple way to do this is

The simplest and best of all optimizations is less workload execution. For example, when an enemy is far away, the perfect time is when the enemy falls asleep. When the player approaches, nothing is done. This is a slow processing method: Function
