title: Can you add a condition into a lambda function?
body: <p>I have the following code:</p>
  
  <p><code>clean_tweets['tweet'] = clean_tweets['tweet'].apply(lambda x: remove_noise(x))</code></p>
  
  <p>I want to add the logic <em>add the condition that remove_noise is done only if the tweet is string</em></p>
  
  <p>Is it possible to achieve this, are there any alternative ways of getting this done?</p>
