如何使用telethon...登录多个帐户？

from telethon.sync import TelegramClient

api_id_1 = 'your_api_id_1'
api_hash_1 = 'your_api_hash_1'
client_1 = TelegramClient('session_name_1', api_id_1, api_hash_1)

api_id_2 = 'your_api_id_2'
api_hash_2 = 'your_api_hash_2'
client_2 = TelegramClient('session_name_2', api_id_2, api_hash_2)

client_1.start()
client_2.start()

# 发送消息示例
client_1.send_message('username', 'Hello from account 1!')
client_2.send_message('username', 'Hello from account 2!')

# 接收消息示例
messages = client_1.get_messages('username')
for message in messages:
    print(message.text)
