title: Remove quotes from String in Python
body: <p>I have a python Code that will recognize speech using the Google STT engine and give me back the results but I get the results in strings with "quotes". I don't want that quotes in my code as I will use it to run many commands and it doesn't work. I haven't tried anything so far as I didn't get anything to try!
  This is the function in the  python code that will recognize speech:</p>
  
  <pre><code>def recog():
      p = subprocess.Popen(['./speech-recog.sh'], stdout=subprocess.PIPE,
                                              stderr=subprocess.PIPE)
      global out,err
      out, err = p.communicate()
      print out
  </code></pre>
  
  <p>This is speech-recog.sh:</p>
  
  <pre><code>#!/bin/bash
  
  hardware="plughw:1,0"
  duration="3"
  lang="en"
  hw_bool=0
  dur_bool=0
  lang_bool=0
  for var in "$@"
  do
      if [ "$var" == "-D" ] ; then
          hw_bool=1
      elif [ "$var" == "-d" ] ; then
          dur_bool=1
      elif [ "$var" == "-l" ] ; then
          lang_bool=1
      elif [ $hw_bool == 1 ] ; then
          hw_bool=0
          hardware="$var"
      elif [ $dur_bool == 1 ] ; then
          dur_bool=0
          duration="$var"
      elif [ $lang_bool == 1 ] ; then
          lang_bool=0
          lang="$var"
      else
          echo "Invalid option, valid options are -D for hardware and -d for duration"
      fi
  done
