title: How to run a python script from html
body: <p>I have been trying to run a python script (<code>rainbow.py</code>) through a HTML button. I have no idea how to do this and all the answers I have found make no sense to me. All I want is a simple explanation of how to run a python script through regular HTML script.</p>
  
  <p>I am trying to do this on a Raspberry Pi.</p>
