如何从目录加载所有文件？

import os

def load_files_from_directory(directory):
    file_list = []
    for filename in os.listdir(directory):
        file_path = os.path.join(directory, filename)
        if os.path.isfile(file_path):
            file_list.append(file_path)
    return file_list

directory = "/path/to/directory"
files = load_files_from_directory(directory)
print(files)
