I want to read multiple csv files in a subfolder(s). I have a main folder, in this main folder many sub folders (here two). I want to read each sub folder, and merge all csv in that subfolder. The merged CSV file name should be the respective subfolder name.
I use the following code, but I am unable to proceed after that, I do not know how to read each subfolder and merge the CVS files.
After merged, I want to read each CSV from output folder, and extract the data in column E (Score).
Kindly some one help.
