原来就这7步,零基础也能搞懂的python数据分析!

原来就这7步,零基础也能搞懂的python数据分析!
还在手动复制粘贴数据表格，自从学会了用python做数据导入和清洗，就再也不想手动复制粘贴了，就像打开的新世界的大门，比Excel透视表的速度快100倍。
为什么要学？这是大家普遍想知道的一个问题，今天把这个话题讲透，首先用python处理百万行数据不卡顿，如果用Excel处理这么多数据早就崩溃了，所以好的工具能够节省很多不必要的麻烦；其次，步骤可重复，不需要手动来回切换sheet，想重复使用只需要下一次换个文件名就可以了；最后就是可以自动画图，尤其是在汇报工作的时候，逼格直接拉满，人在台上讲，图就自动画出来了！
接下来讲讲具体怎么操作，只需要这7步，从数据导入、清洗、可视化、建模一气呵成，涵盖了pandas常用函数，实操性很强！
我把这7步甩给同事，让她照着练了3天，就能独立跑通完整的数据分析项目了，适合学生党、新手小白、职场充电的人，不用死记硬背，理解底层逻辑，边学边练真的很有成就感！
