基于python下的大数据分析（计划篇）
计划用一年的时间学习数据分析的相关知识，以及参加相关竞赛，为以后找工作做铺垫。在这里做笔记，增加自己的印象的同时，对遇到相同问题的小伙伴希望有帮助
个人相关信息
1.目前大三，专业为电子信息工程。 2.学过基础python编程 3.学过基本的概率论及数理统计
个人计划
课时集中在前三天，每周都抽时间学习数据分析类的知识，并完成两篇笔记博客的书写，不定时的更新遇到的问题，以及解决方式。
学习数据分析的原因
1.咱们处于一个网络信息高度发达的21世纪，信息数据非常多，我们可以从这些庞大的数据中，找到有用的信息。 2.现实一点，大数据在目前，尤其是一些大企业需要数据分析师，薪资相当可观。
