Error:
File "C:\Users\prince.bhatia\Desktop\install\copying_module.py", line 10
    "filename", "D:\maharera", "D:\maharera\copy" = argv[1:]

below is my code:

import shutil
import os
import csv
import sys

dataobj = {}
filename = "maharera.csv"


def main(argv):
    filename, "D:\maharera", "D:\maharera\copy" = argv[1:]
    with open(filename, "rb")as csvfile:
        reader = csv.reader(csvfile)
        for row in reader:
            filename = row[0]
            filepath = row[1]

            if filename.startswith("D:\maharera"):
                filename = filename[len(existing_path_prefix):]

            newfile = os.path.join("D:\maharera\copy", filepath)
            print ('Copying %s to %s...' % filename, new_filename),
            shutil.copy(filename, new_filename)
if __main__ == "__main__":
    main(sys.argv)
#source = os.listdir("D:\maharera")
#print(source)
#destination = "D:\maharera\copy"

#for files in source:
#    if files.endswith(".pdf"):
#        shutil.copyfile(files, destination)
