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.
