如何获取拆分后的字符串"/“和"/something”的不同长度

string1 = "/"
string2 = "/something"

length1 = len(string1.split("/")[1])
length2 = len(string2.split("/")[1])

print("拆分后的字符串'/'的长度为:", length1)
print("拆分后的字符串'/something'的长度为:", length2)

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

public class Main {
    public static void main(String[] args) {
        String string1 = "/";
        String string2 = "/something";

        Pattern pattern = Pattern.compile("/(.*)");
        Matcher matcher1 = pattern.matcher(string1);
        Matcher matcher2 = pattern.matcher(string2);

        if (matcher1.find()) {
            int length1 = matcher1.group(1).length();
            System.out.println("拆分后的字符串'/'的长度为: " + length1);
        }

        if (matcher2.find()) {
            int length2 = matcher2.group(1).length();
            System.out.println("拆分后的字符串'/something'的长度为: " + length2);
        }
    }
}
