如何在Py2和Py3上将带有unicode数据的行转换为拉丁文-1编码的csv数据？

import csv
import codecs

with codecs.open('input.csv', 'r', encoding='utf-8') as input_file, \
     codecs.open('output.csv', 'w', encoding='latin-1') as output_file:

    reader = csv.reader(input_file)
    writer = csv.writer(output_file)

    for row in reader:

        converted_row = [element.encode('latin-1') for element in row]
        writer.writerow(converted_row)

import csv
import codecs

with codecs.open('input.csv', 'r', encoding='utf-8') as input_file, \
     codecs.open('output.csv', 'w', encoding='latin-1') as output_file:
    reader = csv.reader(input_file)
    writer = csv.writer(output_file)
    
    for row in reader:
        converted_row = [element.encode('latin-1') for element in row]
        writer.writerow(converted_row)
