title: Python cant convert 'list' object to str error
body: <p>I am using the latest Python 3</p>
  
  <pre><code>letters = ['a', 'b', 'c', 'd', 'e']
  letters[:3]
  print((letters)[:3])
  letters[3:]
  print((letters)[3:])
  print("Here is the whole thing :" + letters)
  </code></pre>
  
  <p>Error: </p>
  
  <pre><code>Traceback (most recent call last):
    File "C:/Users/Computer/Desktop/Testing.py", line 6, in &lt;module&gt;
      print("Here is the whole thing :" + letters)
  TypeError: Can't convert 'list' object to str implicitly
  </code></pre>
