String and dots filling : <p>Write a program (without using loops) which given a string, of size less
than 5, and a positive integer less than 100, prints both of them with
enough dots in between so that the whole string has 20 characters in them.</p>

<p>I know that if I am not using loops I have to use print(..., sep="") supresses the blank between the objects ,printed.</p>

<p>Can somebody tell me How do I restrict new string length to 20 characters?</p>
