使用子进程ssh和执行命令

Question

I need to ssh into the server and execute few commands and process the response using subprocess. Here's my code

command = 'ssh -t -t buildMachine.X.lan; sudo su - buildbot ; build-set sets/set123'
print "submitting command"
result = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stdin=subprocess.PIPE)
print "got response"
response,err = result.communicate()
print response

This is getting stuck. I have seen other threads talking about passing a list instead of string to subprocess and removing shell=True.. I did that too but didn't work.

Ultimately I need the result of last command ie build-set in order to extract some information out of it.. help?

I figured the solution by using univerio's comment

The command needs to be

command = 'ssh -t -t buildMachine.X.lan \'sudo su - buildbot  \'build-set sets/set123\'\''

Individual commands are like argument to previous command. This works.
