本文是 2014 年 12 月我在布拉格经济大学做的名为‘ Python 数据科学’讲座的笔记.欢迎通过 @RadimRehurek 进行提问和评论. 本次讲座的目的是展示一些关于机器学习的高级概念.该笔记中用具体的代码来做演示,大家可以在自己的电脑上运行(需要安装 IPython,如下所示). 本次讲座的听众需要了解一些基础的编程(不一定是 Python),并拥有一点基本的数据挖掘背景.本次讲座不是机器学习专家的“高级演讲”. 这些代码实例创建了一个有效的.可执行的原型系统:一个使用“spam

这篇文章是用来总结python中重要的语法,通过这些了解你可以快速了解一段python代码的含义 Python 的基础语法来带你快速入门 Python 语言.如果你想对 Python 有全面的了解请关注本博客Python的文章,这篇文章也可以当作复习,自己查漏补缺,读者可以在留言区分享自己的 Python 学习和使用心得. 首先聊一下Python的意义 要学好数据分析,一定要掌握 Python 吗?我想,要想学好数据分析,你最好掌握 Python 语言.为什么这么说呢? 首先,在一份关于开发语言
