R:尝试将目录中的多个.txt文件读取到嵌套列表中

import os

def read_files(directory):
    file_list = []
    for filename in os.listdir(directory):
        if filename.endswith(".txt"):
            file_path = os.path.join(directory, filename)
            with open(file_path, "r") as file:
                content = file.read()
                file_list.append(content.splitlines())
    return file_list

directory_path = "目录路径"
nested_list = read_files(directory_path)
