如何拆分字符串以获取文件名？

filename = "example.txt"
file_path = "/path/to/example.txt"

# 使用os.path模块
import os
filename = os.path.basename(file_path)

# 使用字符串分割
filename = file_path.split("/")[-1]

String filePath = "/path/to/example.txt";
String fileName = "";

// 使用Java的File类
import java.io.File;
fileName = (new File(filePath)).getName();

// 使用字符串分割
String[] parts = filePath.split("/");
fileName = parts[parts.length - 1];

const filePath = "/path/to/example.txt";
let fileName = "";

// 使用JavaScript的文件操作库
import * as path from "path";
fileName = path.basename(filePath);

// 使用字符串分割
fileName = filePath.split("/").pop();

$filePath = "/path/to/example.txt";
$fileName = "";

// 使用PHP的pathinfo函数
$pathInfo = pathinfo($filePath);
$fileName = $pathInfo['basename'];

// 使用字符串分割
$parts = explode("/", $filePath);
$fileName = end($parts);
