Python code: explain please
<pre><code>first_num = raw input ("Please input first number. ")
sec_num = raw input (" Please input second number:")
answer = into( first_num) +into( sec_num)

print " Now I will add your two numbers : ", answer

print " Pretty cool. huh ?
print " Now I'll  count backwards from ",answer

counter = answer
while (counter &gt;=0):
    print counter
    counter = counter-1
print " All done !"
</code></pre>

<p>I think the first half in a command to add first and second numbers to get sum and the second half is a command to return to start or zero out. I don't know python language.</p>
