body: <p>How to take a tuple of two equal-size lists from <strong>user input</strong> at a bash terminal from within a python script?
  Let's assume we want the program to register the following tuple</p>
  <pre><code>([0.001, 0.01, 0.1, 1], [1000, 100, 10, 1])
  </code></pre>
  <p>The only condition to grab them is to do that in pairs of two: 0.001, 1000 and then 0.01, 100 and etc.</p>
  <hr />
  <p><strong>Explanation</strong></p>
  <p>the code takes 0.001 and 1000 first</p>
  <p>it then takes 0.01 and 100 second</p>
  <p>it then takes 0.1 and 10 third</p>
  <p>and finally it takes 1 and 1.</p>
  <p>Once it has taken all of them, it will arrange them in the said tuple.</p>
