I am outputting some data to a CSV file but for some reason the method alternates the way in which it outputs the data.The code below is the method being used to output the object to the CSV file.

```
@staticmethod
def OutputCSV(csv_file):
    posts = ApplicationModel.ApplicationModel.getTwitterObjects()
    csv_columns = ['post','sentiment']
    with open(csv_file, 'w') as csvfile:
        writer = csv.writer(csvfile)
        writer.writerow(csv_columns)
        for TwitterObject.TwitterObject in posts:
            writer.writerow({
                TwitterObject.TwitterObject.post,
                TwitterObject.TwitterObject.sentiment
            })

```

The text below is a sample from the outputted CSV file.

```
