I have finished a really short and small import / export script using Python 2.7, and now I would like to structure it using classes and methods where possible.Could anybody give me some advice on what would be the best approach for this?I haven't used any OOP because I would also like somebody to give me some best practices on how this should be done/structured.from similarweb import ContentClientimport csvFILE_OUT = 'similarweb/new_domains.csv'FILE_IN = 'similarweb/domains.csv'content_client = ContentClient(some_key)final_result = with open(FILE_IN, 'r') as csv_read_file:    reader = csv.reader(csv_read_file)    for i, line in enumerate(reader):        url = ', '.join(str(e) for e in line)        final_result += url +   + (content_client.category(url)['Category']) + \nwith open(FILE_OUT, 'w') as csv_write_file:    csv_write_file.write(final_result)
CSV import-export in Python
python;object oriented;python 2.7;csv
Rather than going down the OOP route, I would just split this out into a few functions:import csvfrom similarweb import ContentClientCLIENT_KEY = 'some_key'FILE_IN = 'similarweb/domains.csv'FILE_OUT = 'similarweb/new_domains.csv'def extract_data(path, client):    Extract the data from the specified path using the client.    lines = []    with open(path) as read_file:        for line in csv.reader(read_file):            url = ', '.join(line)  # see note below            lines.append(' '.join(                (url, client.category(url)['Category'])            ))    return '\n'.join(lines)def save_data(path, data):    Save the data to the specified path.    with open(path, 'w') as csv_write_file:        csv_write_file.write(data)      if __name__ == '__main__':    save_data(FILE_OUT, extract_data(FILE_IN, ContentClient(CLIENT_KEY)))Per the documentation:Each row read from the csv file is returned as a list of strings. No automatic data type conversion is performed. so there is no need to explicitly convert to strings.
