如何将第一个 CSV 文件中特定列的数据提取到另一个 CSV 文件中的另一列？

Question

I have two different CSV files which i have imported using pd.read_csv .

Both files have different header names. I would like to export this specific column under the header name of ["Model"] in the first CSV file to the second CSV file under the header name of ["Product"]

I have tried using the following code but produced value error:

writer=df1[df1['Model']==df2['Product']]

Would appreciate any help.

Try joining the DataFrames on the index using pandas.DataFrame.join then exporting the result as a csv using pandas.DataFrame.to_csv .

df1.join(df2)
df1.to_csv('./df2.csv')
