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>

<p>You should probably try to run the code first and play with it to understand it. The code is simple; the first half take two user inputs and add them to each other then it displays the result. </p>

<pre><code>first_num = input("Please input first number:") # get first number input
sec_num = input("Please input second number:")  # get second number input
answer = int(first_num) +int(sec_num)           # add up int values of the numbers
print(" Now I will add your two numbers : ", answer)    # display answer
</code></pre>

<p>As for the second half it takes a number from which it counters downward till zero</p>

<pre><code>print("Now I'll count backwards from ", answer)
counter = answer           # set counter start value
while(counter &gt;=0):        
     print(counter)        # display counter value on each iteration
     counter = counter-1   # decrement counter value on each iteration
print(" All done !)
</code></pre>

<p>I changed your code cause your lines were a bit messy and some incorrect. This version by me works on python3 and <strong>NOT</strong> python2.7.
