title: How to improve this find() function (or similar)
body: <p>I'd like inquire about how to improve this working code to skip execution of [i] if one of the four stop words is found in [table_t1.keys].</p>
  
  <pre><code>for i in table_t1.keys():
      if i.find("data") == -1:
          if i.find("split") == -1:
              if i.find("loss") == -1:
                  if i.find("prob") == -1:
                      #do something
  </code></pre>
  
  <p>Using the find-function is not required.</p>
