简单的UDP服务器收发程序

说明：  onenote强大的插件，类似思维脑图，结构化部署，(OneNote powerful plug-in, similar to mind maps.)

python实现126邮箱自动登录源码，需要一些类库支持才能运行，请先下载相关类库.(python achieve 126 mailboxes automatically log source, need some support in order to run the library, please download library.)

python入门教材，涵盖了python语言的基础教学，并包括三个联手项目（1，外星人入侵游戏 2，数据可视化 3，Web应用程序）(Python Introductory textbook)

这是一个基于Python和Numpy函数库的手写识别系统实现，使用了KNN（K近邻算法）进行一个手写识别的简单实现。 能对手写数字0-9进行识别分类，来推断识别，也就是说要利用sklearn来训练一个K最近邻（k-Nearest Neighbor，KNN）分类器，用于识别数据集DBRHD的手写数字(This is a handwritten recognition system based on Python and Numpy function library, using KNN (K nearest neighbor algorithm) to implement a handwritten recognition. The handwritten number 0-9 can be classified and classified to infer recognition, that is, to use sklearn to train a K nearest neighbor (k-Nearest Neighbor, KNN) classifier to identify the handwritten numbers of the data set DBRHD.)

说明：  18个项目，通过前9天的数据，预测第10天PM2.5的含量，采用线性回归，损失函数为均方根误差(Through the data of the first nine days, the PM2.5 content of the 10th day was predicted for 18 projects, and linear regression was adopted, and the loss function was root mean square error.)

了解基本编程知识，熟悉编程算法，用Python编写奇偶分数求和函数。(Understanding basic programming knowledge, familiar with programming algorithms, using Python to write odd and even fraction summation function.)

说明：  模糊聚类对iris数据集分类，测试结果显示较好的准确率(Classification of iris data sets by fuzzy clustering)

【实例简介】找到的最好的XGBoost算法学习资料，分享给大家！

说明：  讲解Python的基本使用方法，包括数据结构，生成器，迭代器和网络编程(Explain the basic usage of Python)

该程序用于Python读取vision research 公司phantom 高速相机的cine文件(this file is for reading cine files recorded by vision research phantom high speed camera)
