title: Compare two integers for similarity
body: <p>Example:</p>
  
  <pre><code>number1 = 54378
  number2 = 54379
  if number1 (is similar to) number2:
     print (number1 + " " + number2)
     input("what to do")
  </code></pre>
  
  <p>I would like to compare between these two numbers, and let the program notify me when this kind of (between number1 and number2 ) similarity happens.</p>
  
  <p>I would like the solution to be flexible with some room for more similarities (_ust the first digit is different).</p>
  
  <p>BTW, I am using Python 3.X</p>
