title: 3 values (numbers) in 1 input separation. Python 3
body: <p>I'm working on a code right now that a part of it requires to ask the user for 3 different numbers in one line ( could be any number of digits in each number).
  Say I ask the user for the input and he enters : "31 722 9191".
  A space is required between the numbers. How would you go about separating these numbers and assigning a variable to each one of them. So for example 31 would be "A", 722 would be "B" and so on...
  What I've got so far:</p>
  
  <pre><code>user_input = input(" Please enter the numbers: ")
  </code></pre>
  
  <p>Thanks !</p>
