我有一个如下所示的数据框:
Labels
1 Nail_Polish,Nails
2 Nail_Polish,Nails
3 Foot_Care,Targeted_Body_Care
4 Foot_Care,Targeted_Body_Care,Skin_Care
我想生成以下矩阵:
Nail_Polish Nails Foot_Care Targeted_Body_Care Skin_Care
1 1 1 0 0 0
2 1 1 0 0 0
3 0 0 1 1 0
4 0 0 1 1 1
我怎样才能做到这一点？
最佳答案
使用str.get_dummies :
df2 = df['Labels'].str.get_dummies(sep=',')
结果输出:
Foot_Care Nail_Polish Nails Skin_Care Targeted_Body_Care
1 0 1 1 0 0
2 0 1 1 0 0
3 1 0 0 0 1
4 1 0 0 1 1
