无法从csv中的urls中删除第一个和最后一个字符

import csv

# 读取csv文件
with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    data = list(reader)

# 提取urls列
urls_column = [row[0] for row in data]

# 删除第一个和最后一个字符
updated_urls = [url[1:-1] for url in urls_column]

# 更新csv文件
for i in range(len(data)):
    data[i][0] = updated_urls[i]

with open('data.csv', 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerows(data)
