如何按列连接两个数据框？

Question

I have two dataframes df1 and df2 containing an equal number of columns. I want to create another dataframe df by joining df1 and df2 .

The resulting dataframe should be formed by selecting column1 from df1 and column1 from df2 and join them together. Similarly column2 from df1 and column2 from df2 and so on.

Answer 1

Try this:

You can replace 'Column 1' and 'Column 2' with whatever name is required in your context.

import pandas as pd

df = pd.merge(df1, df2, on=['Column 1','Column 2'], how = 'outer')
