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!


              1234567891011121314151617
            
# 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")

Opgave

Modify your previous function (name new as people_information_mod) so now it will detect if the name is in the dictionary. If not, print "There is no information about name"
