如何使用python删除csv文件中的这些字符？

import csv
import re

with open('input.csv', 'r') as file_in, open('output.csv', 'w', newline='') as file_out:
    reader = csv.reader(file_in)
    writer = csv.writer(file_out)

    for row in reader:
        new_row = [re.sub(r'特定字符', '', cell) for cell in row]
        writer.writerow(new_row)

import csv
import re

with open('input.csv', 'r') as file_in, open('output.csv', 'w', newline='') as file_out:
    reader = csv.reader(file_in)
    writer = csv.writer(file_out)
    
    for row in reader:
        new_row = [re.sub(r'特定字符', '', cell) for cell in row]
        writer.writerow(new_row)
