根据子字符串拆分列表元素

def split_list_by_substring(lst, substring):
    new_lst = []
    for item in lst:
        new_lst.extend(item.split(substring))
    return new_lst

# 示例用法
my_list = ['apple-orange', 'banana', 'cherry-grape']
substring = '-'
result = split_list_by_substring(my_list, substring)
print(result)

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

public class SubstringSplitter {
    public static List<String> splitListBySubstring(List<String> list, String substring) {
        List<String> newList = new ArrayList<>();
        for (String item : list) {
            String[] splitItems = item.split(substring);
            for (String splitItem : splitItems) {
                newList.add(splitItem);
            }
        }
        return newList;
    }

    // 示例用法
    public static void main(String[] args) {
        List<String> myList = new ArrayList<>();
        myList.add("apple-orange");
        myList.add("banana");
        myList.add("cherry-grape");
        String substring = "-";
        List<String> result = splitListBySubstring(myList, substring);
        System.out.println(result);
    }
