Writing your own functions (4/5)

By this time we always returned some information in the function body. But rarely we don't need to return and save any values after function execution, for example, if we need to just print something.

# data countries_dict = {'USA': (9629091, 331002651), 'Canada': (9984670, 37742154), 'Germany': (357114, 83783942)} countries_dict["Brazil"] = (8515767, 212559417) countries_dict["India"] = (3166391, 1380004385) # define a function def country_information(d, name): print("Country:", name) print("Area:", d[name][0], 'sq km') print("Population:", round(d[name][1]/1000000, 2), 'mln') # test our function country_information(countries_dict, "Brazil") country_information(countries_dict, "Germany")
