如何将字符串切断为给定长度的子字符串

def split_string(string, length):
    return [string[i:i+length] for i in range(0, len(string), length)]

string = "这是一个很长的字符串，需要将其切断为给定长度的子字符串"
length = 5
substrings = split_string(string, length)
print(substrings)

function splitString(string, length) {
    let substrings = [];
    for (let i = 0; i< string.length; i += length) {
        substrings.push(string.slice(i, i + length));
    }
    return substrings;
}

let string = "这是一个很长的字符串，需要将其切断为给定长度的子字符串";
let length = 5;
let substrings = splitString(string, length);
console.log(substrings);

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static List<String> splitString(String string, int length) {
        List<String> substrings = new ArrayList<>();
        for (int i = 0; i< string.length(); i += length) {
            substrings.add(string.substring(i, Math.min(i + length, string.length())));
        }
        return substrings;
    }

    public static void main(String[] args) {
        String string = "这是一个很长的字符串，需要将其切断为给定长度的子字符串";
        int length = 5;
        List<String> substrings = splitString(string, length);
        System.out.println(substrings);
    }
