Why is this displaying None?
<pre><code>def characterLine(firstChar,secondChar,phrase):
     '\n' + ((str(firstChar)+str(secondChar))*(len(phrase)/2)+len(phrase)%2* firstChar)
</code></pre>

<p>So the second part of the code will display but when I try to concatenate it with a line skip, it displays "None."</p>

<p>Can someone explain to me as to why this is happening?</p>
