I have two .csv files that I want to save as df using pandas (python). In df1, there is just one column with 15 title names. I want to use these to rename the last 15 columns of df2. I know how to manually rename df columns. Is there a special code I can use to achieve the same task? Beware, there are 5 initial columns in df2 that I still need to rename manually when saving df2 in python. Please share a clear code or lines of codes. Thank you
