如何在命令行应用程序中打印当前行？

import sys

def print_current_line():
    for i, arg in enumerate(sys.argv):
        print(f"{i}: {arg}")

if __name__ == "__main__":
    print_current_line()

import java.util.Arrays;

public class PrintCurrentLine {
    public static void main(String[] args) {
        Arrays.stream(args).forEach(System.out::println);
    }
}

const args = process.argv.slice(2);

function printCurrentLine() {
    args.forEach((arg, index) => {
        console.log(`${index}: ${arg}`);
    });
}

printCurrentLine();

#include<iostream>

int main(int argc, char *argv[]) {
    for (int i = 0; i < argc; ++i) {
        std::cout << i << ": "<< argv[i]<< std::endl;
    }
    return 0;
}

using System;

class PrintCurrentLine {
    static void Main(string[] args) {
        for (int i = 0; i< args.Length; i++) {
            Console.WriteLine($"{i}: {args[i]}");
        }
    }
}
