body: <p>How do I add a dot into a Python list?</p>
  
  <p>For example</p>
  
  <pre><code> groups = [0.122, 0.1212, 0.2112]
  </code></pre>
  
  <p>If I want to output this data, how would I make it so it is like </p>
  
  <pre><code>122, 1212, 2112
  </code></pre>
  
  <p>I tried write(groups...[0]) and further research but didn't get far. Thanks.</p>
  
  <p>Thankyou</p>
