df2
slot
2
91
62
58
我需要输出df3作为
slot Time Location User
2 2017-10-27 00:30:00 54 1
91 2017-11-01 22:45:00 78 1

62 2017-11-02 15:30:00 99 1
58 2017-11-02 14:30:00 477 2
如果这些是csv文件,那么我们可以加入它们
join File1 file2 > file3
但是我们如何对Jupyter笔记本中的输出执行相同的操作
答案 0 :(得分:1)
尝试isin
:
df1[df1.slot.isin(df2.slot)]
输出:
slot Time Location User
