title: How to loop through my 2d array?
body: <p>I have an array which created with this:</p>
  
  <pre><code>numbers = []
  for num in range(0,5): 
        nums = []
        for inum in range(0,5):
            nums.append(inum) 
  
        numbers.append(nums)
  </code></pre>
  
  <p>How to loop through? I tried <code>for item in len(numbers):</code> but it doesn't work.</p>
