title: Removing NaN Values from csv
body: <p>I have searched several questions around this topic but have not found and answer that made my code work. I'm a beginner so any help is much appreciated. </p>
  
  <p>I'm using the jupyter notebook and have the following code:</p>
  
  <pre><code>import pandas
  a = pandas.read_csv("internal_html.csv")
  a.dropna(axis="columns", how="any")
  a.head(10)
  </code></pre>
  
  <p>I get no error when running the code, but the columns with NaN values still show up. </p>
  
  <p>Thanks!</p>
