数据转换指的是对数据的过滤、清理以及其他的转换操作。移除重复数据DataFrame里经常会出现重复行,DataFrame提供一个duplicated()方法检测各行是否重复,另一个drop_duplicates()方法用于丢弃重复行:duplicated()和drop_duplicates()方法默认判断全部列,如果不想这样,传入列的集合作为参数可以指定按列判断,例如 ...

很显然,在这种复杂的情况下直接用drop_duplicates是不管用的,所以我们必须想其他的方法。 下面我们通过加工一组特征来辅助我们进行去重的筛选,对id和time分组统计status个数、求和。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 dup_grp=(df_dup.groupby(['id','time']).agg(stat_cnt=('status','coun...
