Question

I have a python script on my local machine.Is there any way to run this script on remote machine.I mean python script should on the local machine but execution should happen on remote machine and get the output back to the local machine.

Answer 1

The pathos package has tools that make it easy to interact with remote machines, all directly from python… and you can also easily capture stdout or other piped responses and return them to your calling script.

So, let's say you have a local script hello.py that looks like this:

# 'hello.py'
import os
print os.system('hostname')

They you can push the script and execute it like this:

>>> import pathos
>>> c = pathos.core.copy('hello.py', destination='guido.remote.com:~/hello.py')
>>> s = pathos.core.execute('python hello.py', host='guido.remote.com')
>>> print s.response()
guido
0
>>> s.pid()
37429

There's also ssh-tunneling, setting up daemon processes, remote port pickling, and dealing with killing remote processes… if you need that stuff.

pathos provides an abstraction on remote commands, the default being ssh and scp… but it's easy to see what it's doing.

>>> s.message
'ssh -q guido.remote.com "python hello.py"'
>>> c.message
'scp -q -r hello.py guido.remote.com:~/hello.py'
