title: Cloudformation wildcard search with boto3
body: <p>I have been tasked with converting some bash scripting used by my team that performs various cloudformation tasks into Python using the boto3 library. I am currently stuck on one item. I cannot seem to determine how to do a wildcard type search where a cloud formation stack name contains a string.</p>
  
  <p>My bash version using the AWS CLI is as follows:</p>
  
  <pre><code>aws cloudformation --region us-east-1 describe-stacks --query "Stacks[?contains(StackName,'myString')].StackName" --output json &gt; stacks.out
  </code></pre>
  
  <p>This works on the cli, outputting the results to a json file, but I cannot find any examples online to do a similar search for contains using boto3 with Python. Is it possible?</p>
  
  <p>Thanks!</p>
