如何拆分文件路径以获取文件名？[复制]

import os

def get_filename_from_path(path):
    return os.path.basename(path)

# 示例
path = "/home/user/documents/report.pdf"
filename = get_filename_from_path(path)
print(filename)  # 输出: report.pdf

const path = require('path');

function getFilenameFromPath(filePath) {
    return path.basename(filePath);
}

// 示例
const filePath = '/home/user/documents/report.pdf';
const filename = getFilenameFromPath(filePath);
console.log(filename);  // 输出: report.pdf

import java.nio.file.Paths;

public class FileNameExtractor {
    public static String getFilenameFromPath(String path) {
        return Paths.get(path).getFileName().toString();
    }

    public static void main(String[] args) {
        String path = "/home/user/documents/report.pdf";
        String filename = getFilenameFromPath(path);
        System.out.println(filename);  // 输出: report.pdf
    }
}

using System.IO;

public class FileNameExtractor
{
    public static string GetFilenameFromPath(string path)
    {
        return Path.GetFileName(path);
    }

    public static void Main(string[] args)
    {
        string path = "/home/user/documents/report.pdf";
        string filename = GetFilenameFromPath(path);
        Console.WriteLine(filename);  // 输出: report.pdf
    }
}
