title: Python - print table-like data cleanly
body: <p>I have output that looks like this</p>
  
  <pre><code>AB%CD3_SW3Z_1000 uvsec_czrkup_rmplr SeightRveZargrp def_move 35.8% 28.0% 16.2% 120 0.0010
  MN%P03_AT%W00_500 uvsec_czrkup_rmplr SeightRveZargrp def_move 28.8% 24.7% 23.4% 94 0.1000
  KE_A03_UVA%Q00_100 uvsec_czrkup_rmplr SeightRveZargrp def_move 27.2% 11.8% 3.5% 398 0.010

  <p>What is the cleanest, most elegant way to format it as</p>
  
  <pre><code>AB%CD3_SW3Z_1000   uvsec_czrkup_rmplr SeightRveZargrp def_move 35.8% 28.0% 16.2% 120 0.0010
  MN%P03_AT%W00_500  uvsec_czrkup_rmplr SeightRveZargrp def_move 28.8% 24.7% 23.4% 94 0.1000
  KE_A03_UVA%Q00_100 uvsec_czrkup_rmplr SeightRveZargrp def_move 27.2% 11.8% 3.5% 398 0.010
  </code></pre>
  
  <p>Of course, I am asking in general case, assuming each line has the same number of tokens. I want columns to be left-alligned.</p>
