如何使用字符串查找列表？

def find_elements_with_string(target_string, lst):
    result = []
    for element in lst:
        if target_string in element:
            result.append(element)
    return result

# 示例用法
my_list = ["apple", "banana", "orange", "grape"]
target = "an"
found_elements = find_elements_with_string(target, my_list)
print(found_elements)
