title: Converting amazon data into csv format in Python
body: <p>all, I asked similar question before but haven't solved it yet. </p>
  
  <p>I have amazon review data set and would like to convert it into csv format in Python. The original data that I have look like as follows:</p>
  
  <pre><code>product/productId: B00032K32A
  product/title: Cruiser Accessories 21330 Slim Rim, Chrome License Plate Frame
  product/price: 4.99
  review/userId: A2O41UFL8HAQWV
  review/profileName: Nick Nefsik
  review/helpfulness: 4/4
  review/score: 5.0
  review/time: 1239667200
  review/summary: It's slim, alright!
  review/text: Similar to another review, I also found that this frame is more of a overlay to a   license plate (sits on top of the plate), as opposed to securing the plate underneath it, if that makes sense.It *just* covers the edges of my AZ plate, which is fine, but I sure wouldn't want it to be any smaller around its outside perimeter. I also ordered the chrome covers for the screws (Cruiser Accessories 82030 Screw Covers, Chrome) that I was already using, and, altogether, it looks great, and is exactly the look I was going for.

  review/summary: Nice...
  review/text: I first purchased these for my new 2008 Honda Accord EX-L to complement the chrome on the car and though they looked nice I eventually ordered the 20130 version of the Cruiser chrome frame for the wider border.

  <p>The result should look like this:</p>

  <p>I have pretty big amount of data (more than 300MB) with the same format above so want to write it instead of printing it. </p>
  
  <p>I am a newbee to python and tried several different ways but still haven't succeeded it yet. Are there anyone who has a good thought about converting the original data type into csv format?</p>
