import re

def replace_numbers(text, replacement='X'):
    return re.sub(r'\d', replacement, text)

# 示例
original_string = "Hello 123 World 456"
modified_string = replace_numbers(original_string)
print(modified_string)  # 输出: Hello XXX World XXX

function replaceNumbers(text, replacement = 'X') {
    return text.replace(/\d/g, replacement);
}

// 示例
const originalString = "Hello 123 World 456";
const modifiedString = replaceNumbers(originalString);
console.log(modifiedString);  // 输出: Hello XXX World XXX

import java.util.regex.*;

public class ReplaceNumbers {
    public static String replaceNumbers(String text, String replacement) {
        return text.replaceAll("\\d", replacement);
    }

    public static void main(String[] args) {
        String originalString = "Hello 123 World 456";
        String modifiedString = replaceNumbers(originalString, "X");
        System.out.println(modifiedString);  // 输出: Hello XXX World XXX
