title: Printing numbers in a row without using string
body: <p>I am new to python and I was practicing my coding skills with Hacker rank. I came across a question where I have to print numbers in a series one after another without adding any new line or white space in between them and most important is I cannot use the string method to get desired output.</p>
  <p>For example if
  input is</p>
  <p><code>3</code></p>
  <p>then output should be</p>
  <p><code>123</code></p>
  <p>How can do it without string?</p>
  <p>Please guide me...</p>
  <p>Thanks in advance</p>
