title: Retrieving Values with p.expect
body: <p>I have a program that logs into a server and issues commands. The results are printed out at the end of the script. The below code shows the script I have created to pass commands through ssh.</p>
  
  <pre><code>import pexpect
  
  ssh_newkey = 'Are you sure you want to continue connecting'
  # my ssh command line
  p=pexpect.spawn('ssh user@00.00.00.00')
  
  i=p.expect([ssh_newkey,'password:',pexpect.EOF])
  if i==0:
      print "I say yes"
      p.sendline('yes')
      i=p.expect([ssh_newkey,'password:',pexpect.EOF])
  if i==1:
      print "I have entered the password. I will now flip camera through ",
      p.sendline("user")
      i=p.expect('user@hol-NA:')
      p.sendline("cd /opt/ad/bin")
      i=p.expect('user@hol-NA:')
      p.sendline("./ptzflip")
      i=p.expect('user@hol-NA:')
  elif i==2:
      print "I either got key or connection timeout"
      pass
  results = p.before # print out the result
  
  print results
  </code></pre>
  
  <p>The results that the program prints out is:</p>
  
  <pre><code>Value = 1800
  Min = 0
  Max = 3600
  Step = 1
  </code></pre>
  
  <p>I want to capture the values that are printed out.</p>
  
  <p>In reponse to the questions below. I want to capture eg. 'Value' as a variable and '1800' as its value. I have tried to separate it in a dictionary as mentioned below but I get an error. When I enter:</p>
  
  <pre><code>results_dict = {} 
  for line in results: 
      name, val = line.split(' = ') 
      results_dict[name] = val
  </code></pre>
  
  <p>I get an error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "ptest.py", line 30, in &lt;module&gt;
      name, val = line.split(' = ') 
  ValueError: need more than 1 value to unpack
  </code></pre>
  
  <p>When I check this code in Python it stores these values as a string. It stores it as:</p>
  
  <pre><code>'/opt/ad/bin$ ./ptzflip\r\nValue = 1800\r\nMin = 0\r\nMax = 3600\r\nStep = 1\r\n'
  </code></pre>
  
  <p>Can anyone help in this problem. Thanks</p>
