调用客户端

test.py

import time
from ssh_client import ParamikoClient

begin = time.time()

client = ParamikoClient('config.ini')
client.connect()
client.run_cmd()

query_num = 100
query_fre = 10
while query_num > 0:
    now = time.time()
    now - begin > query_fre
    print(time.time())
    begin = now
    query_num = query_num - 1
