title: Smartsheet Data Tracker: AttributeError: 'dict' object has no attribute 'append'
body: <p>I am new to Python and I'm working with Smartsheet Data Tracker to update a sheet from a CSV file.</p>
  
  <p>I have problems about the array list management in Python; I don't know about this error, I was reading about this error on StackOverflow but I don't understand it:</p>
  
  <p>The error:</p>
  
  <pre><code>"File "C:\Users\David\DataTraker\connectors\CSVCon.py", line 61, in __init__     
      self.csvData.append(readerRow)
  AttributeError: 'dict' object has no attribute 'append'"
  </code></pre>
  
  <p>And my code:</p>
  
  <pre><code>def __init__(self, sourceConfig):
      self.csvData = []
  
  
      self.csvData = {"sourceId": "siniestros",
                      "connectorClassName": "CSVCon",
                      "fileName": "siniestros.csv",
                      "isStrict": False}
  
      for readerRow in sourceReader:
          self.csvData.append(readerRow)
  </code></pre>
