title: Double Progress Bars for Jupyter/PyCharm
body: <p>I've some code that needs to run over two loops of not insignificant length. So what I'd like to be able to do is have two progress bars; one for each loop.  </p>
  
  <pre><code>for _ in tqdm(range(10)):
      for _ in tqdm(range(100)):
          time.sleep(0.01)
  </code></pre>
  
  <p>I thought that <code>tqdm</code> supported this, and it appears that it does if I run in IPython. However, if I run inside a Jupyter notebook, or in PyCharm, instead of updating the bar(s) after each loop it prints each update on a new line.  </p>
  
  <p>I assume that this is something specific to the way that printing works. Has anyone figured out a way to make multiple progress bars work inside a notebook, or in PyCharm.</p>
