How to use readlines to read from file and return the abbreviation of item
<p>file looks like this:</p>

<pre><code>BURGER KING
BRG
MCDONALDS
MCDNLDS
WENDYS
WNDY
</code></pre>

<p>Example:</p>

<pre><code>food('abbreviations.txt')

Enter a fast food place: McDonalds

Abbreviation: MCDNLDS

Enter a fast food place:

Thank you!
</code></pre>

<p>so far:</p>

<pre><code>infile = open(filename, 'r')

l = infile.readlines()

infile.close()
</code></pre>

<p>but I don't know what to do after readlines</p>
