从CSV中删除非ASCII字符

import csv

def remove_non_ascii(text):
    return ''.join([i if ord(i) < 128 else '' for i in text])

input_csv = 'input.csv'
output_csv = 'output.csv'

with open(input_csv, 'r', encoding='utf-8') as infile, open(output_csv, 'w', encoding='utf-8') as outfile:
    reader = csv.reader(infile)
    writer = csv.writer(outfile)

    for row in reader:
        clean_row = [remove_non_ascii(field) for field in row]
        writer.writerow(clean_row)
