title: Python: Pandas Dataframe Using Wildcard to Find String in Column and Keep Row
body: <p>I have a pandas data frame.  Below is a sample table. </p>
  
  <pre><code>Event   Text
  A       something/AWAIT hello          
  B       la de la
  C       AWAITING SHIP
  D       yes NO AWAIT 
  </code></pre>
  
  <p>I want to only keep rows that contain some form of the word AWAIT in the Text column.  Below is my desired table: </p>
  
  <pre><code>Event   Text
  A       something/AWAIT hello          
  C       AWAITING SHIP
  D       yes NO AWAIT 
  </code></pre>
  
  <p>Below is the code I tried to capture strings that contain AWAIT in all possible circumstances.  </p>
  
  <pre><code>df_STH001_2 = df_STH001[df_STH001['Text'].str.contains("?AWAIT?") == True]
  </code></pre>
  
  <p>The error I get is as follows: </p>
  
  <pre><code>error: nothing to repeat at position 0
  </code></pre>
