Exploring the predictive variables

It is always useful to get a better understanding of the population. Therefore, one can have a closer look at the predictive variables. Recall that you can select a column in a pandas DataFrame by indexing as follows:

basetable["variable"]

To count the number of occurrences of a certain value in a column, you can use the sum method: 

sum(basetable["variable"]==value)

In this exercise you will find out whether there are more males than females in the population.
