title: Split list of strings into column by spaces
body: <p>I have a list of strings in python:</p>
  
  <pre><code>list =['Observed on Date 56370 at 850 F, -0.272 +/- 1.035', 
         'Observed on Date 56372 at 849 F, 0.051 +/- 0.945',
         'Observed on Date 56381 at 850 F, 0.101 +/- 0.353',]
  </code></pre>
  
  <p>I would like to split this into an array with columns delimited at each space in each string.</p>
  
  <p>I'm not sure where to start with this, and any help is appreciated!</p>
