title: Convert Any Iterable to Array in Python
body: <p>This just <em>has</em> to be a dupe, but I just didn't find any existing instance of this question...</p>
  
  <p>What is the easiest way to convert any iterable to an array in Python (ideally, without importing anything)?</p>
  
  <p><strong>Note</strong>: Ideally, if the input is an array then it shouldn't duplicate it (but this isn't required).</p>
