Dataframe column tolist(): column object is not callable

Question

I am trying to make a list of column values of an existing dataframe named datadf.

datadf = sqlContext.createDataFrame(data[0:], ('Name', 'Date', 'Lat', 'Lon', 'Number'))
print(type(datadf))
datadf.printSchema()

Returns:

<class 'pyspark.sql.dataframe.DataFrame'>
root
 |-- Name: string (nullable = true)
 |-- Date: string (nullable = true)
 |-- Lat: double (nullable = true)
 |-- Lon: double (nullable = true)
 |-- Number: long (nullable = true)

datadf.show()

Returns:

+-----------------+----------+-----------+-----------+------+
|             Name|      Date|        Lat|        Lon|Number|

only showing top 20 rows

The dataframe has latitude and longitude values, basically I want to make a python list of each.

import pandas

latlist = datadf['Lat'].tolist()
latlist = datadf['Lat'].values.tolist()

Both return: 'Column' object is not callable

Now, I suspect something is wrong with the dataframe values, as I ran into this error before. I have a basemap of the Netherlands, and I want to simply add these coordinates as points on this map.
