在正则表达式中获取字符之间的字符串

Hello (.*?) World

import re

string = "Hello World"
pattern = r"Hello (.*?) World"
match = re.search(pattern, string)
if match:
    result = match.group(1)
    print(result)

import java.util.regex.Matcher;
import java.util.regex.Pattern;

String string = "Hello World";
String pattern = "Hello (.*?) World";
Pattern regex = Pattern.compile(pattern);
Matcher matcher = regex.matcher(string);
if (matcher.find()) {
    String result = matcher.group(1);
    System.out.println(result);
}
