title: Save pre-formatted column-view lists to .txt file - Python
body: <p>thanks for helping.</p>
  
  <p>This python code format my lists into column-view style:</p>
  
  <pre><code>for ele1,ele2,ele3 in zip(I,a,F):
     print('{:&lt;10}{:&lt;10}{:&lt;}'.format(ele1,ele2,ele3))
  </code></pre>
  
  <p>where I,a,F are previously done lists of the same size. The question is: How do I save this result into a .txt file?</p>
  
  <p>Thanks.</p>
