Python with SFTP library fails with correct code

Here is my code:

import pysftp

cnopts = pysftp.CnOpts()
cnopts.hostkeys = None   

host = "192.168.8.104"
username = "pi"
password = "raspberry"

local_path = "C:\Users\helencecilia\Desktop\Basura\Conexion SFTP\download.txt" 
remote_path = "\home\pi\helloworld.txt"

with pysftp.Connection(host, username, password, cnopts=cnopts) as sftp:
    sftp.put(local_path, remote_path)

Error message:

C:\Python27\lib\site-packages\pysftp\__init__.py:61: UserWarning: Failed to load HostKeys from C:\Users\helencecilia\.ssh\known_hosts.  You will need to explicitly load HostKeys (cnopts.hostkeys.load(filename)) or disableHostKey checking (cnopts.hostkeys = None).
  warnings.warn(wmsg, UserWarning)

    data = self._read_private_key_file('RSA', filename, password)
  File "C:\Python27\lib\site-packages\paramiko\pkey.py", line 267, in _read_private_key_file
    with open(filename, 'r') as f:

The third argument must be private_key, not password according to the API documentation:

class pysftp.Connection(host, username=None, private_key=None, password=None, port=22, private_key_pass=None, ciphers=None, log=False, cnopts=None, default_path=None)

Either pass None for the private_key argument:

pysftp.Connection(host, username, None, password, cnopts=cnopts)

or better, use keyword arguments:

pysftp.Connection(host=host, username=username, password=password, cnopts=cnopts)
