Label the data

A dataframe df is available having columns endword: string, features: vector, and outvec: vector. You are to select the rows where endword equals "him", and add a column label having the integer value 1. Then, use the union operation to add an equal number of rows having endword not equals to him, such that these additional rows have label = 0.

As a reminder, in SQL the not equals comparison is done using <>.
