title: Concatenation Operator + or ,
body: <pre><code>var1 = 'abc'
  var2 = 'xyz'
  
  print('literal' + var1 + var2) # literalabcxyz
  print('literal', var1, var2) # literal abc xyz
  </code></pre>
  
  <p>... except for automatic spaces with ',' whats the difference between the two? Which to use normally, also which is the fastest?</p>
  
  <p>Thanks</p>
