python连接远程服务器执行shell脚本并传输文件

需要对数据进行维护，每次复制粘贴太麻烦，同事已经在本地实现了大部分功能，现在在已有的代码上添加自动更新数据的脚本

import paramiko
import logging
import time
import os

file_path1 = "aaaaaaaaaaa"
file_path2 = "aaaaaaaaaa"

target_path1 = "xxxxxxxxxxxx"
target_path2 = "ccccccccccccccccc"

file_list = [xxxxxxxxxxxxxx]


class SSHConnection:
    def __init__(self, host="xxxxxxxx", port=22, username="xxx", password="xxxxxxxxx"):
        self.host = host
        self.port = port
        self.username = username
        self.password = password

    def connect(self):
        transport = paramiko.Transport((self.host, self.port))
        transport.connect(username=self.username, password=self.password)
        self.__transport = transport

    def close(self):
        self.__transport.close()

    def upload(self):
        sftp = paramiko.SFTPClient.from_transport(self.__transport)
