只要六步,就能搞定40%的Python数据分析难题
你是否也对满屏的报错无从下手？
这是很多新手会面临的问题，感觉按照学的东西做的，但是用的时候还是不知道为什么会报错。当你学明白了，你会发现原来80%的日常分析任务，其实就建立在不到20个基础操作之上。
今天就是给大家分享六步简单的操作，不仅轻松上手，而且还能应对工作中80%的数据预测问题：
在使用之前当然是需要安装好工具，常用的工具有PyCharm和Visual Studio Code，准备好之后就可以开始操作了。
步骤一：导入必要的库
步骤二：数据准备和探索
步骤三&步骤四：数据拆分&模型训练与预测
步骤五&步骤六：模型评估&结果解释和报告
数据预测有什么重要意义呢？其中最重要的意义在于能够通过过去的数据对明天的经营做出预判，比如仓库备货，如果遇到电商节或者促销，应该储备多少货才不会断销同时不会有大量积压，所以在工作中有大量且广泛的应用！
