title: pyspark: counter part of like() method in dataframe
body: <p>Is there any counter method for like() in spark dataframe (something as notLike())?</p>
  
  <p>Or is there any other way to do it except using the traditonal SQL query?</p>
  
  <p>I want to do just the opposite of the following:</p>
  
  <pre><code>df.where(col("_c2").like("XY6%")).show(5)
  </code></pre>
