遍历序列文件将数据合并写入新文件

import os

file_path = r'*********'    # 序列文件路径
for parent, dirnames, filenames in os.walk(file_path):  # 遍历路径下全路径
    for filename in filenames:  # 遍历全路径下全文件名
        full_path = os.path.join(parent, filename)  # 组装完整文件路径
        print(full_path)
        file_read = open(full_path, mode='r', encoding='utf8')  # 读取路径内容
        print(file_read.readline())
        file_write = open('merge_data.txt', 'a', encoding='utf8')   # 创建写入对象，按全量方式写入
        file_write.writelines(file_read)    # 将读取的内容合并写入新的文件
        file_read.close()
        file_write.close()
