我正在寻找一种方法来计算一列中的值的数量,并证明它比我原先想象的更棘手.
Percentile Percentile1 Percentile2 Percentile3
0 mediocre contender contender mediocre
69 mediocre bad mediocre mediocre
117 mediocre mediocre mediocre mediocre
144 mediocre none mediocre contender
171 mediocre mediocre contender mediocre
我正在尝试创建类似于以下输出的内容.它需要四个选项并按列计算.它本质上是每列的pd.value.counts.任何帮助肯定会受到赞赏.
Percentile Percentile1 Percentile2 Percentile3
mediocre: 5 2 3 4
contender: 0 1 2 1
bad: 0 1 0 0
none: 0 1 0 0
