learning python the hard way exercise 17
<p>Getting too many values to unpack from line 4 in module. </p>

<pre><code>script, from_file, to_file = argv  line.
</code></pre>

<p>exercise 17 example</p>

<pre><code> from sys import argv
 from os.path import exists

 script, from_file, to_file = argv 
</code></pre>

<p>I know I'm doing something stupid. Using python version 2.7.3</p>

<p>This is verbatim copy and paste from the exercise:</p>

<pre><code>from sys import argv
from os.path import exist

script, from_file, to_file = argv
</code></pre>

<p>Ive tried both the solutions and get an Invalid sytax error</p>
