title: Appending two arrays together in Python
body: <p>I've been working in Python with an array which contains a one-dimensional list of values. I have until now been using the array.append(value) function to add values to the array one at a time.</p>
  
  <p>Now, I would like to add all the values from another array to the main array instead. In other words I don't want to add single values one at a time. The secondary array collects ten values, and when these are collected, they are all transfered to the main array. The problem is, I can't simply use the code 'array.append(other_array)', as I get the following error:</p>
  
  <pre><code>unsupported operand type(s) for +: 'int' and 'list'
  </code></pre>
  
  <p>Where am I going wrong?</p>
