title: Change indentation level in Google Colab
body: <p>I am using <a href="https://colab.research.google.com" rel="nofollow noreferrer">Google Colab</a> to write Python code in their notebooks. Whenever I hit <code>enter</code> after a loop or conditional, the new line is automatically indented, which is good, but it uses only 2 whitespaces by default. This is contrary to the <a href="https://www.python.org/dev/peps/pep-0008/#indentation" rel="nofollow noreferrer">PEP-8 standard</a> which recommends 4 whitespaces.</p>
  <p>Why is this the case and how can I change this setting within Colab?</p>
