In the context of this exercise, what values are we passing in for the
estimator parameter when we create a barplot?
When we use the
estimator parameter, we pass in objects that are
Basically, callable objects are like functions, which we can call.
The functions we pass for the
estimator parameter must only be functions that can apply to list values.
As a result, we can pass in values like,
len which are functions that apply to lists. However, we cannot use functions like
int since these do not apply to lists.
