Python是一种面向对象、解释型计算机程序设计语言，其应用领域非常广泛，包括数据分析、自然语言处理、机器学习、科学计算以及推荐系统构建等。 本书用Python语言来讲解算法的分析和设计。本书主要关注经典的算法，但同时会为读者理解基本算法问题和解决问题打下很好的基础。(Python is an object-oriented, interpretive computer programming language. It has a wide range of applications, including data analysis, natural language processing, machine learning, scientific computing and recommendation system construction. This book uses Python language to explain the analysis and design of algorithms. This book focuses on classical algorithms, but at the same time it will lay a good foundation for readers to understand basic algorithms and solve problems. The book consists of 11 chapters. The tree, graph, counting problem, inductive recursion, traversal, decomposition and merging, greedy algorithm, complex dependency, Dijkstra algorithm, matching and cutting problem, difficult problem and its dilution are introduced. The book has exercises and reference materials at the end of each chapter, which provides readers with more convenience for self-examination and further stu)

数据时代已经到来，但数据分析、数据挖掘人才却十分短缺，据全球顶尖管理咨询公司麦肯锡(McKinsey)一份详细分析报告显示： 预计到2018年，大数据或者数据工作者的岗位需求将激增，其中大数据科学家的缺口在14万到19万之间，对于懂得如何利用大数据做决策的分析师和经理的岗位缺口则将达到150万！ 先来了解一下数据分析，就是以商业目的为驱动，所开展的获取数据、处理数据、分析数据、展示数据和撰写数据结构报告的一系列科学过程。 针对这个过程，R都有相应的方法可以较好地处理和完成数据分析所涉及到的内容。R是一种免费的、开源的语言和操作环境，其初衷是为了统计计算和画图，但是R语言现在能够做的事情已经远远地超出了其初衷，可以在诸多领域进行应用，比如，数据挖掘、机器学习、社交网络、生物信息、金
