SQL queries for filtering Table

In the previous exercise, you have run a simple SQL query on a DataFrame. There are more sophisticated queries you can construct to obtain the result that you want and use it for downstream analysis such as data visualization and Machine Learning. In this exercise, we will use the temporary table people that you created previously and filter out the rows where the "sex" is male and female and create two DataFrames.

Remember, you already have SparkSession spark and people temporary table available in your workspace.
