title: How to extract the p-value from the scipy result
body: <p>I have the following code to run Wilcoxon rank-sum test </p>
  
  <pre><code>print stats.ranksums(pre_course_scores, during_course_scores)
  
  RanksumsResult(statistic=8.1341352369246582, pvalue=4.1488919597127145e-16)
  </code></pre>
  
  <p>However, I am interested in extracting the pvalue from the result. I could not find a tutorial about this. Can someone help?</p>
