I am automating tasks and I am new in Python, so I would like your help because I need to run a Shell script on another machine and this command I need to give inside a Python code.
I thought I’d wear something like:
#!/usr/bin/python
# -*- coding: utf8 -*-
import subprocess
subprocess.call('ssh user@host', shell=True)
But that’s why, because I don’t know how I would implement Login and Password (as well as "yes" of cryptography).

I imagine you want to make an SSH connection via python. If so, the pxssh module does exactly what you want. For example, to run 'ls -l' and to print the output, you need to do something like this:
import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
print "SSH falha no login."
print str(s)
else:
print "SSH sucesso no login"
s.sendline ('ls -l')
s.prompt()
print s.before
s.logout()

I did this what you said and used the rsa keys. It really helped a lot. The difficulty now is to run the linux commands inside the machine that was accessed. Meu código simples ficou assim:

##############################################
#! /usr/bin/python
# -- coding: utf8 -- import subprocess subprocess.call('echo Running Shell inside Python', shell=True) subprocess.call('ssh <user>@<localhost>', shell=True) subprocess.call('echo I’m in <localhost>', shell=True) ###################################################Xa;; It accesses the machine, but inside it does not echo.

I think you will have to "study" a little more. If you have access to both machines the best thing to do is to work with keys
rsaand configure the file~/.ssh/config, so you don’t need to keep moving password, user name and not even host address, so make it easy for once your life use the Fabric and be happy.– Sidon
I forgot to mention the plumbum, in case you want to go the way seemingly easier.
