title: How do I configure gitlab-ci.yml for a simple hello world program in Gitlab
body: <p>I wanted to know how to configure the correct <code>.gitlab-ci.yml</code> file so that it'll automatically detect errors within the code that I've committed into my project.</p>
  
  <p>for example I will create a new python file <code>helloworld.py</code>:</p>
  
  <pre><code>print("hello world""
  </code></pre>
  
  <p>There is a clear error within the code above, and I want my <code>.gitlab-ci.yml</code> to be able to test that code and make sure it will not pass.</p>
  
  <p>How do I do this guys? I really appreciate any help on this.</p>
