> There’s an error in the astype() documentation, as it uses cast instead of astype. It should probably include a mention that astype is an alias for cast (and vice versa in the cast documentation): https://spark.apache.org/docs/latest/api/python/pyspark.sql.html#pyspark.sql.Column.astype 
> The same error occurs with drop_duplicates and dropDuplicates: https://spark.apache.org/docs/latest/api/python/pyspark.sql.html#pyspark.sql.DataFrame.drop_duplicates 
> The issue here is we are copying the code.  According to [~davies] the easiest way is to copy the method and just add new docs.
