python read multiple column file into array
<p>I'm trying to read a file that looks like:</p>

<pre><code>Protein in water

<p>I have to strip the first 2 lines and read the different columns separately. 
I have tried this:</p>

<pre><code> with open('file.txt') as fa:
     for line_aa in fa.readlines()[3:11]:
         line_aa = line_aa.strip()
         print line_aa
         col1,col2,col3,col4,col5,col6,col7,col8,col9 = line_aa.split('\t',9)
</code></pre>

<p>but I get the following error:</p>

<pre><code>300LEU      H 2946   8.110  15.548  13.027 -0.0632  0.8718 -0.8443
Traceback (most recent call last):
File "rmsd_cg_vs_aa.py", line 50, in &lt;module&gt;
col1,col2,col3,col4,col5,col6,col7,col8,col9 = line_aa.split('\t',9)
ValueError: need more than 1 value to unpack
</code></pre>

<p>What am I missing here?</p>
