title: How do you suppress a warning/error in Python and or Cloud9 IDE?
body: <p>I am using the Cloud9 IDE and have created a Python project.</p>
  
  <p>However, I keep getting the error in my editor on one line, which is not an error when i run it, which says:</p>
  
  <pre><code>Instance of 'dict' has no 'columns' member
  </code></pre>
  
  <p>How can I suppress this error, either using Python syntax or Cloud9 syntax?</p>
  
  <p>NOTE: when I run the code, it does not result in an error. My IDE editor simply thinks its an error and warns me.</p>
  
  <pre><code>    xl      = pd.ExcelFile(dataFileUrl)
      sheets  = xl.sheet_names
      data    = xl.parse(sheets[0])
  
  
      # the ERROR warning is on the line for data.columns
      for ecol in expectedCols:
          if (ecol in data.columns) == False:
              return {
                  'fail':   True,
                  'code':   402,
                  'msg':    "Incomplete data. Missing: " + ecol
              }
  </code></pre>
