我有三个pandas.Dataframe像这样：
df1
A_1 A_2 A_3
MAC
ID1 1.0 1.0 2.0
ID2 6.0 6.0 7.0
ID3 1.0 2.0 3.0
df2
B_1 B_2 B_3
MAC
ID1 1.0 1.0 1.0
ID2 2.0 2.0 3.0
ID3 1.0 1.0 1.0
df3
C_1 C_2 C_3
MAC
ID1 1.0 1.0 2.0
ID2 5.0 5.0 5.0
ID3 1.0 2.0 3.0
我想pd.merge或pd.concat预期结果如下：
MAC A_1 B_1 C_1 A_2 B_2 C_2 A_3 B_3 C_3
ID1 1.0 1.0 1.0 1.0 1.0 1.0 2.0 1.0 2.0
ID2 6.0 2.0 5.0 6.0 2.0 5.0 7.0 3.0 5.0
ID3 1.0 1.0 1.0 2.0 1.0 2.0 3.0 1.0 3.0
我在这个链接中搜索了https://pandas.pydata.org/pandas-docs/stable/merging.html，但结果并不像我预期的那样。 提前感谢您的回答。
