是否可以生成只读CSV文件？

import csv

data = [['Name', 'Age', 'City'],
        ['John', '25', 'New York'],
        ['Alice', '30', 'San Francisco'],
        ['Bob', '35', 'London']]

filename = 'data.csv'

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

# 设置文件权限为只读
import os
os.chmod(filename, 0o444)

import java.io.FileWriter;
import java.io.IOException;
import com.opencsv.CSVWriter;

String[] header = {"Name", "Age", "City"};
String[] row1 = {"John", "25", "New York"};
String[] row2 = {"Alice", "30", "San Francisco"};
String[] row3 = {"Bob", "35", "London"};

String filename = "data.csv";

try (CSVWriter writer = new CSVWriter(new FileWriter(filename))) {
    writer.writeNext(header);
    writer.writeNext(row1);
    writer.writeNext(row2);
    writer.writeNext(row3);
}

// 设置文件权限为只读
File file = new File(filename);
file.setReadOnly();
