嗨,我有一个如下数据框
id other_things Dist_1 Dist_2
1 a 20.3 16.4
2 b 15.4 480.2
3 a 12.6 480.2
4 c 20.3 16.4
5 d 12.6 480.2
6 e 52.5 584.5
我希望在列#34; Dist_1"列中找到值对匹配的行和" Dist_2"。如下,
id other_things Dist_1 Dist_2
1 a 20.3 16.4
4 c 20.3 16.4
3 a 12.6 480.2
5 d 12.6 480.2
谢谢。

这看起来像你想要的:
df[df.duplicated(['Dist_1','Dist_2'], keep=False)]
id other_things Dist_1 Dist_2
0 1 a 20.3 16.4
2 3 a 12.6 480.2
3 4 c 20.3 16.4
4 5 d 12.6 480.2
如果排序很重要:
df[df.duplicated(['Dist_1','Dist_2'], keep=False)].sort_values('Dist_2')
id other_things Dist_1 Dist_2
0 1 a 20.3 16.4
3 4 c 20.3 16.4
2 3 a 12.6 480.2
4 5 d 12.6 480.2
