Writing your own functions (5/5)

But what if in our examples we pass as country argument some inappropriate name or name which does not exist in our dictionary? Let's predict it with some conditional statements!

# data countries_dict = {'USA': (9629091, 331002651), 'Canada': (9984670, 37742154), 'Germany': (357114, 83783942)} countries_dict["Brazil"] = (8515767, 212559417) countries_dict["India"] = (3166391, 1380004385) # modify our function def country_information_mod(d, name): if name not in d.keys(): print("There is no information about", name) else: print("Country:", name) print("Area:", d[name][0], 'sq km') print("Population:", round(d[name][1]/1000000, 2), 'mln') # test our function country_information_mod(countries_dict, "Ukraine") country_information_mod(countries_dict, "USA")
