title: AttributeError: 'list' object has no attribute 'lower' gensim
body: <p>I have a list of 10k words in a text file like so:</p>
  
  <p>G15
  KDN
  C30A
  Action Standard
  Air Brush
  Air Dilution</p>
  
  <p>I am trying to convert them into lower cased tokens using this code for subsequent processing with GenSim:</p>
  
  <pre><code>data = [line.strip() for line in open("C:\corpus\TermList.txt", 'r')]
  texts = [[word for word in data.lower().split()] for word in data]
  </code></pre>
  
  <p>and I get the following callback:</p>
  
  <pre><code>AttributeErrorTraceback (most recent call last)
  &lt;ipython-input-84-33bbe380449e&gt; in &lt;module&gt;()
        1 data = [line.strip() for line in open("C:\corpus\TermList.txt", 'r')]
  ----&gt; 2 texts = [[word for word in data.lower().split()] for word in data]
        3 
  AttributeError: 'list' object has no attribute 'lower'
  </code></pre>
  
  <p>Any suggestions on what I am doing wrong and how to correct it would be greatly appreciated!!! Thank you!!</p>
