In this exercise, we will add a new column in the dataset using the withColumn method, and later, using the drop function, will remove it. Now, let's perform the following steps:

Add a new column in a Spark DataFrame using the withColumn method:df = df.withColumn('Half_sepal_width', df['Sepalwidth']/2.0)

Use the following command to show the dataset with the newly added

Figure 4.10: Introducing new column, Half_sepal_width
