如何在python中将多个文件存储在一个文件中？

import pickle

def store_files_in_one(files, output_file):
    data = []
    for file in files:
        with open(file, 'rb') as f:
            file_data = f.read()
            data.append(file_data)
    
    with open(output_file, 'wb') as f:
        pickle.dump(data, f)

# 示例用法
files = ['file1.txt', 'file2.txt', 'file3.txt']
output_file = 'output.pkl'
store_files_in_one(files, output_file)
