title: Lock.acquire(False) does?
body: <p>I have a piece of code</p>
  
  <pre><code>    locked = lock.acquire(False)
          if locked:  break
  </code></pre>
  
  <p>according to python doc:<br>
  <strong>lock.aquire(False):-
  When invoked with the blocking argument set to False, do not block. If a call with blocking set to True would block, return False immediately; otherwise, set the lock to locked and return True.</strong>
  I quite understand what they said but can somebody simplify this and please explain me in relation to the above code.</p>
