line ="Hello"

print stdout.readlines()
I want to pass the "line" content to echo. But i get [u'\\n'] as output.
I have also tried echo \\$line, echo "$line". But not getting hello as output.
The remote shell can't access to your program variables, the command must be composed before its launch.
stdin, stdout, stderr = ssh_client.exec_command('echo "{0}"'.format(line))
Be aware of safety issues ( Thanks @Tripleee ), in Python 3 use shlex.quote
to increase the robustness of your code:
stdin, stdout, stderr = ssh_client.exec_command('echo {}'.format(quote(line)))
