title: is there an equivalent __reload__ function as to __import__?
body: <p>I only know the module name during runtime, and as such this is how it looks like:-</p>
  
  <pre><code>a = 'mymodule'
  __import__(a)
  </code></pre>
  
  <p>but along the way, when mymodule.py is changed, i wanna reload it again.
  is there a command like</p>
  
  <pre><code>__reload__(a)
  </code></pre>
  
  <p>?</p>
