Adding first character of a string to each of the other characters : <p>I have a string <code>alphabet = "abcdefghijklmnopqrstuvwxyz"</code>
I need output like this 
<code>
aa
ab
ac
ad
ae
af
...
ay
az
</code>
how would I add the first character to every one of the other characters and print it? 
Thanks!</p>
