Copy space delimited string columns to list
<p>I am trying to copy the content of a space delimited .txt file into separate lists corresponding to the columns, but I could not find a way to solve this.</p>

<p>A sample of a .txt file is this:</p>

<p>If I split the file using the space delimiter, the columns will be (commas are included in some columns):</p>

<pre><code>Product

Mode: 
,
Satellite: 
Sentinel-2, 
Size:
5.07
GB
</code></pre>

<p>What I tried doing is (example for the first column):</p>

<pre><code>list = []
with open('D:\GIS\Sentinel\cmd_output.txt', 'r') as file:
    reader = csv.reader (file, delimiter = ' ')
    for a,b,c,d,e,f,g,h,i,j,k,l,m,n in reader:
        list.append(a) 
print list
</code></pre>

<p>But it doesn't work and send the error:</p>

<blockquote>
  <p>ValueError: need more than 1 value to unpack</p>
</blockquote>

<p>How can I do this for each of the columns in file?
Thanks!</p>
