title: Progress Bar in Python Console on Windows
body: <p>I have gone through the below two links in addition to some others and I have tried most all examples and suggestions provided, but in my output the progress bar is not getting updated, rather new one shows, either end of same line or alternately on the new line. What am I missing here, can someone please guide me.</p>
  
  <p><a href="https://stackoverflow.com/questions/3160699/python-progress-bar">Python Progress Bar</a></p>
  
  <p><a href="https://stackoverflow.com/questions/3173320/text-progress-bar-in-the-console">Text Progress Bar in the Console</a></p>
  
  <p>For ease, I am reproducing some of the codes (from examples of above threads) I have tried and their outputs. Did I understand incorrect that it will update the same line or what am I missing. Appreciate your help. I am using Python 3.4 on Windows 7 and getting the output on console (no GUI).</p>
  
  <p>Example 1:</p>
  
  <pre><code>import progressbar
  import time, sys
  
  progress = progressbar.ProgressBar()
  for i in progress(range(80)):
      time.sleep(0.01)
  </code></pre>

  <p><strong>Edit: You can see that printing on the same line is happening, but it is appending at the end of the last print rather than overwriting which is the desired effect. Thanks!</strong></p>
