如何将我的数据输出为CSV

import csv

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

filename = 'output.csv'

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

print('Data has been exported to', filename)

import java.io.FileWriter;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class CSVExporter {
    public static void main(String[] args) {
        List<String[]> data = new ArrayList<>();
        data.add(new String[]{"Name", "Age", "City"});
        data.add(new String[]{"John", "25", "New York"});
        data.add(new String[]{"Alice", "30", "San Francisco"});
        data.add(new String[]{"Bob", "35", "London"});

        String filename = "output.csv";

        try (FileWriter writer = new FileWriter(filename)) {
            for (String[] row : data) {
                writer.write(String.join(",", row) + "\n");
            }
            System.out.println("Data has been exported to " + filename);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
