工欲善其事必先利其器,在使用Python做数据挖掘和数据分析时,一大必不可少的利器就是Pandas库了。pandas 是基于NumPy 的一种工具,该工具是为了解决数据分析任务而创建的,其纳入了大量库和一些标准的数据模型,提供了高效地操作大型数据集所需的工具。
下面就从创建数据、查看数据、筛选数据、统计数据、缺失值处理、数据可视化等14个方面介绍Pandas数据处理的基本操作,希望对广大数据爱好者有所帮助。
1、创建数据
<figure style="box-sizing: inherit; margin: 24px 0px; color: rgb(51, 51, 51); font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Microsoft YaHei", "Source Han Sans SC", "Noto Sans CJK SC", "WenQuanYi Micro Hei", sans-serif; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial;">image
</figure>

说明一下,本人现在也还只是一个学生,目前算数据菜鸟一枚,因为自己即将参加17年的校招,需要梳理所学知识,就顺便将将其进行一下分享,如果对您有所帮助,那甚好;如果没有,还请大神们自动屏蔽掉。
