[英]python multithreading, how can i run multiple operations at once
am trying to sftp to remote machine 正在尝试通过sftp到远程计算机
with my function 用我的功能
def copyToServer(hostname, username, password, destPath, localPath):
transport = paramiko.Transport((hostname, 22))
transport.connect(username=username, password=password)
sftp = paramiko.SFTPClient.from_transport(transport)
sftp.put(localPath, destPath)
sftp.close()
transport.close()
and i want to copy file to multiple servers in parallel 我想将文件并行复制到多个服务器
if have tried this 如果尝试过这个
for i in range(xxx.xxx.xxx.111-xxx.xxx.xxx.210):
hostname = i
username = defaultLogin
password = defaultPassword
thread = threading.Thread(target=copyToServer, args=(hostname, username, password, destPath, localPath))
thread.start()
this gave me error 这给了我错误
