So for a coordinate, we saw that you could find the distance between two coordinates. Maybe for our abstract animal object, you might have it make a sound, by maybe printing to the screen or something like that. How to define a class (recap) class Animal (object): def __init__ (sel...

Let's use these coordinates, place them in more descriptive variable names, then create a bounding box to make a geometry object representing the extent of our dataframe. Finally we'll draw it on the a map: df_geoextent_geom = df.spatial.bbox df_geoextent_geom m1 = gis.map("United ...
First, note that we do not check the types of the parameters of the speeding_ticket and the make_payment methods, nor do we check the types of any of the parameters of the constructor. This could lead to the program crashing if the user provides an argument that was not expected. For ...
