在数字和字符之间插入空格

import re

def insert_spaces(text):
    return re.sub(r'(\d)([a-zA-Z])', r'\1 \2', text)

# 示例
text = "hello123world456"
result = insert_spaces(text)
print(result)  # 输出: hello 123 world 456

function insertSpaces(text) {
    return text.replace(/(\d)([a-zA-Z])/g, '$1 $2');
}

// 示例
const text = "hello123world456";
const result = insertSpaces(text);
console.log(result);  // 输出: hello 123 world 456

import java.util.regex.*;

public class Main {
    public static String insertSpaces(String text) {
        return text.replaceAll("([0-9])([a-zA-Z])", "$1 $2");
    }

    public static void main(String[] args) {
        String text = "hello123world456";
        String result = insertSpaces(text);
        System.out.println(result);  // 输出: hello 123 world 456
