title: partial carraige return in python
body: <p>I'm trying to add prints inside nosetests run that show how much of the test has passes, but I do not want to use full carriage return.</p>
  
  <p>It should look like:</p>
  
  <p>my_test_module.MyTestCase.test_somthing 10%</p>
  
  <p>my_test_module.MyTestCase.test_somthing 20%</p>
  
  <p>...</p>
  
  <p>my_test_module.MyTestCase.test_somthing 100%</p>
  
  <p>my_test_module.MyTestCase.test_somthing ok</p>
  
  <p>all in the same line.</p>
  
  <p>I cannot use "\r" because it will override the entire line. I need a way to use some "partial carriage return" of a given number of letters.</p>
  
  <p>How can I do it?</p>
