title: python selenium TimeUnit - where to import from
body: <p>I'm using Python selenium version 3.0.1 in which it seems that instead of saying </p>
  
  <pre><code>driver.implicitly_wait(10)
  </code></pre>
  
  <p>we must now say</p>
  
  <pre><code>driver.implicitly_wait(10, TimeUnit.SECONDS)
  </code></pre>
  
  <p>This gives me the error ...</p>
  
  <p><em>NameError: name 'TimeUnit' is not defined</em></p>
  
  <p>So I need to import TimeUnit, but where (what module) do I import it from?</p>
  
  <p>The documentation link at <a href="https://pypi.python.org/pypi/selenium" rel="noreferrer">https://pypi.python.org/pypi/selenium</a> takes me to selenium 2 documentation, and typing TimeUnit into the search box there draws a blank.  So anyone who wants to tell me to read the docs needs to tell me where the right docs are.</p>
