Upload file via SFTP with Python

I wrote a simple code to upload a file to a SFTP server in Python. I am using Python 2.7.

import pysftp

srv = pysftp.Connection(host="www.destination.com", username="root",
password="password",log="./temp/pysftp.log")

srv.cd('public') #chdir to public
srv.put('C:UsersXXXDropboxtest.txt') #upload file to nodejs/

# Closes the connection
srv.close()

The file did not appear on the server. However, no error message appeared. What is wrong with the code?

I have enabled logging. I discovered that the file is uploaded to the root folder and not under public folder. Seems like srv.cd('public') did not work.

I found the answer to my own question.

import pysftp

srv = pysftp.Connection(host="www.destination.com", username="root",
password="password",log="./temp/pysftp.log")

with srv.cd('public'): #chdir to public
    srv.put('C:UsersXXXDropboxtest.txt') #upload file to nodejs/

# Closes the connection
srv.close()

Put the srv.put inside with srv.cd
