title: Printing Simple Diamond Pattern in Python
body: <p>I would like to print the following pattern in Python 3.5 (I'm new to coding): </p>
  
  <pre><code>    *
     ***
    *****
   *******
  *********
   *******
    *****
     ***
      *
  </code></pre>
  
  <p>But I only know how to print the following using the code below, but not sure how to invert it to make it a complete diamond:</p>
  
  <pre><code>n = 5
  
  print("Pattern 1")
  
  for a1 in range (0,n):
      for a2 in range (a1):
          print("*", end="")
      print()
  
  for a1 in range (n,0,-1):
      for a2 in range (a1):
          print("*", end="")
      print()
  
  *
  **
  ***
  ****
  *****
  ****
  ***
  **
  *
  </code></pre>
  
  <p>Any help would be appreciated!</p>
