How can I run a python script which is stored in my local machine on another database server?

I have a python script on my local machine related to a database. I can log in to that database server through a SSH connection. But how can I run my python file on that database server?
Do I need to upload my python script on that server machine? How can I do that?
I logged in to the database server through the ssh connection. I have access to that.
I ran my python file which is stored in my local machine on that server.
It shows "python3: can't open file .. No such file or directory"
I want to run the program and see the output.

Jupyter Notebook: Execution on Remote Server: are Files Written to Remote Server?

I want to execute a Jupyter Notebook on a remote server.
If I use this:
with open('somefile.txt', 'a') as the_file:
the_file.write('Hello\n')
Is the file saved on the local or the remote file system?

Yes, the file will be saved into the remote file system. You can make use of applications like Filezilla if you are using Linux OS or you can use Winscp for windows to retrieve the files.

Copy File from Windows Host to Linux [Python]

What are the different modules/ways to copy file from a windows computer to a linux server available in python
I tried using ftplib api to connect to the windows server but i m unable to do with the error - socket.error: [Errno 111] Connection refused
What are the other modules that i can connect to a windows computer to copy or list the files under a directory

If you have access to linux server, and the file generated on windows automatically, you can do the folowing:
Generate ssh-key on your windows maching
Add it to authorized_hosts of the linux machine
Install simple console scp tool on windows
Write simple cmd-script to copy file with help of scp, something like:
scp c:\path\to\file.txt user#linuxhost.local:/home/user/file.txt
Run this script automatically every time, then the file is generated on windows host.

Error when connecting to SFTP server using Python Pysftp

I am executing a Python script on my Linux server that uses pysftp to connect to another server in order to read files that are sitting in a directory of that remote server. When I run the script, it fails out while connecting to the remote server and creates a text file with the title: 'This service allows sftp connections only.'
This file is created inside my project directory. Below is the part of my code that is failing:
def sftp_get_file(sftp_host, sftp_username):
with pysftp.Connection(sftp_host, sftp_username) as sftp:
# transfer file from remote to local
sftp.get(remote_file, local_file)
Code is very simple and works when I've tested it using my local server as the remote server. When I tested it in the new environment by actually depending on SFTP, then it failed. Any suggestions? Is pysftp using SSH at some point when it should be using only SFTP?

Turns out the problem was due to me performing sftp.execute('ls') a couple lines down in the script. The server I was remoting onto only supported sftp commands and that command was forbidden.
