title: How do I remove all the zero's from a dataset that is in a list?
body: <p>I have this dataset in an excel spreadsheet and I have converted into a csv file for python to read:</p>
  
  <pre><code>1   5   0   1   3   2   1   18  30  50  13  12  24  1
  0   1   0   0   1   1   1   10  10  12  10  6   16  -1
  0   7   0   0   4   4   1   21  30  46  19  11  25  1
  0   1   0   0   1   1   1   2   4   3   4   2   5   -1
  0   1   0   0   1   1   1   4   4   7   3   6   6   -1

  <p>From this I need an output file in python format which prints in lists without the 0's. In other words, each row or column should not have any zero's. Please look below at the example format that should be printed.</p>

  <p>EDIT:</p>
  
  <p>import csv
  list_new = []</p>
  
  <p>with open('testingSeta.csv') as csvfile: </p>
  
  <pre><code> for row in csv.reader(csvfile):
       row.insert(0, row.pop())
       list_new.append(row)
  
   list_new.pop(0)
  </code></pre>
  
  <p>print list_new</p>
  
  <p>There are no zeros on their own. This is what I have so far. Please help. Thank You</p>
