CsvConverter.py

import csv

with open('input.csv', 'rb') as input, open('output.csv', 'wb') as output:
    reader = csv.reader(input, delimiter=';')
    writer = csv.writer(output, delimiter=';')
    for input_row in reader:
        firstname, name, accno, bsc, amount = input_row
        output_row = [name, '%s %s' % (firstname, name), accno, bsc, amount]
        writer.writerow(output_row)

# For Jython 2.5, the context manager usage ('with') has to be replaced with a classic try..finally.
# For Python 3.x, the files have to be opened in text mode ('r', 'w') instead of binary mode ('rb', 'wb').
