title: Power BI, Power Query - Go trough list and add text with each step (for each)
body: <p>I have a list for example:</p>
  
  <pre><code>A
  B
  C
  D
  </code></pre>
  
  <p>Now I want to create a query in power query that will create a text like this:</p>
  
  <p>"The letters are: "  A B C D</p>
  
  <p>I already have this query:</p>
  
  <pre><code>let
      xx=   KEYListfunction(),
      list = Text.Split(xx, ","),
      text = "",
     loop = List.Accumulate(list, 0, (state, current) =&gt; text = text &amp;  " " &amp; current ))
  in
  loop
  </code></pre>
  
  <p>But the result only says "FALSE"</p>
