Exercise 1.3.3

• Create a new function in this module that returns the average life expectancy on a given continent for a given year. Call this function with different arguments and compare the results.

To validate this function, enter the following line of code:

                
            avg_life_exp = gapminder.avg_life_exp_by_continent_and_year(gapminder_filepath, 'Europe', '2007')
print(avg_life_exp)

The output should look like this:

                
            Europe life expectancy 2007
