How to compare variables and find difference in python
<p>I have two variables readARP and readFPING which will have a series of IP's listed in them and I want to compare one to the other. After comparing them I would like to print out the difference if there is any.</p>

<pre><code>readARP = scanProcess.read()
readFPING = fpingscanPocess.read()

&gt;&gt;&gt; print readARP
192.168.1.1
192.168.1.100
192.168.1.1

&gt;&gt;&gt; print readFPING
192.168.1.1
192.168.2.1
192.168.1.12
</code></pre>

<p>I want to compare both and then print 192.168.2.1 192.168.1.12 192.168.1.100 since they are unique to the two.</p>

<p>P.S. What is "readFPING" referred to as in python I have adapted the term variable</p>

<p>After I find out what is different how could I add the different to a variable. 
Example: 192.168.1.2 isnt in readFPING but I then want to add it (Creating a master ip list)</p>
