Python Move a File from Remote Machine to Local

I am new in python and trying different stuff.

Currently trying to copy a text file to_copy.txt from a remote machine with local ip 192.168.1.101 to my current machine.

What i tried from googling does not seem to work.

import paramiko
from scp import SCPClient

ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect("[email protected]", password="look420")
print("Connected")
scp = SCPClient(ssh.get_transport())
scp.get("/home/testme/target_folder/to_copy.txt")
scp.close()

But, when i run this i get error;

Traceback (most recent call last):
  File "/home/uc/Python_Projects/MoveFileAndFolder/move_remote.py", line 7, in <module>
    ssh.connect("[email protected]", password="look420")
  File "/usr/local/lib/python3.4/dist-packages/paramiko/client.py", line 296, in connect
    to_try = list(self._families_and_addresses(hostname, port))
  File "/usr/local/lib/python3.4/dist-packages/paramiko/client.py", line 200, in _families_and_addresses
    addrinfos = socket.getaddrinfo(hostname, port, socket.AF_UNSPEC, socket.SOCK_STREAM)
  File "/usr/lib/python3.4/socket.py", line 530, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -2] Name or service not known

What i am doing wrong here?

NOTE: Current machine is running Debian Jessie and the remote machine runs Ubuntu 14.04.4 LTS

Download file resources from a remote server to a local through paramiko

        check_local_dir(local_dir_name)
        print('Start downloading folder: ' + remote_dir_name)

        for remote_file_name in sftp.listdir(remote_dir_name):
            sub_remote = os.path.join(remote_dir_name, remote_file_name)
            sub_remote = sub_remote.replace('\\', '/')
            sub_local = os.path.join(local_dir_name, remote_file_name)
            sub_local = sub_local.replace('\\', '/')
            down_from_remote(sftp_obj, sub_remote, sub_local)

        sftp.get(remote_dir_name, local_dir_name)


def check_local_dir(local_dir_name):
    "" "whether the local folder exists, create if it does not exist" ""
    if not os.path.exists(local_dir_name):

    password = 'password'
    port = 22
    # Remote file path (absolute path required)
    remote_dir = '/data/nfs/zdlh/pdf/2018/07/31'
    # Local file storage path (either absolute or relative)
    local_dir = 'file_download/'

    # Connect to remote server
    t = paramiko.Transport((host_name, port))
    t.connect(username=user_name, password=password)
    sftp = paramiko.SFTPClient.from_transport(t)

    # Remote file start download
    down_from_remote(sftp, remote_dir, local_dir)

    # Close connection
    t.close()

Did you try

ssh.connect("192.168.1.101", username="testme", password="look420")

Please refer Doc

The port for scp (22) is likely not open on the remote machine. Please check with a command line call to confirm that you can indeed make an ssh or scp connection.
