copy files from one destination to another by reading filename from csv

[Prince_Bhatia]

ok what i am trying to do is ...writing a module that will read csv , pick file names from there look into the directory where these files resides and then move them to the destination folder...i think i had some error in the above code..i have redone the same code..

but now it says

Error:
no file path or directory "filepath"

below is the code

import os
import shutil
import csv
import sys

csv_file = "maharera.csv"
existing_path_prefix = "D:\maharera"
new_path_prefix = "D:\movement"

def main(argv):
  # TODO: this should do some error checking or maybe use optparse
  csv_file, existing_path_prefix, new_path_prefix = argv[1:]

  with open(csv_file, 'r') as f:
    reader = csv.reader(f)
    for row in reader:
      # Assuming the column in the CSV file we want is the first one
      filename = row[0]
      filepath = row[1]

      if filename.startswith(existing_path_prefix):
        filename = filename[len(existing_path_prefix):]

      new_filename = os.path.join(new_path_prefix, filename)

      #print ('Copying %s to %s...' % filename, new_filename),
      #print ('Copying %s to %s...' % filepath, new_filename)  #Changed
      shutil.copy(filepath, new_filename)   #Changed
      print ('done.')
#print ('All done!')


if __name__ == '__main__':
  main(sys.argv)

i read the code here...https://stackoverflow.com/questions/29850220/read-filenames-from-csv-and-then-copy-the-files-to-different-directory

please help me to correct this code so that i can move selected files which are mentioned in csv to new directory...i have attached new cvs file for this code also by editing the original post..
