Practical Programming, 2nd Edition

Exercises

Here are some exercises for you to try on your own. Solutions are available at http://pragprog.com/titles/gwpy2/practical-programming.

1. In this exercise, you will implement class Country, which represents a country with a name, a population, and an area.

   1. Here is a sample interaction from the Python shell:

      >>> canada = Country('Canada', 34482779, 9984670)

      'Canada'
      >>> canada.population
      34482779
      >>> canada.area
      9984670

      The code above cannot be executed yet because class Country does not exist. Define Country with a constructor (method __init__) that has four parameters: a country, its name, its population, and its area.

   2. Consider this code:

      >>> canada
