Modify a SSH command via Python

Question

After establishing an SSH connection I've tried the following command to move a file from one folder to another one and renaming it:

command='cp /test/trial test/attempt/trial_something'  
ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command(command)

and it worked. Now I've tried, without success, to modify the command in this way:

command_test='/test/trial'
command='cp command_test test/attempt/trial_something'  
print (command)
ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command(command)

the result of the print is

cp command_test test/attempt/trial_something

so basically the string is not build as the one in first example.

instead of ssh, you can use os.system()

I think I've found a way:

command_test='/test/trial'
command='cp ' + command_test + ' test/attempt/trial_something'  
print (command)
ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command(command)

this worked to me.
