for loop (5/5)
We haven't already discussed how can we use for loop to iterate over dictionaries, as this data structure completely differs from others. If you try to iterate just over a dictionary, it will iterate over its keys. So, it's the same that iterating over dict.keys().
In the previous section we saved countries as a dictionary too. And this time it will be much understandable how to print information. Let's see
# data countries_dict = {'USA': (9629091, 331002651), 'Canada': (9984670, 37742154), 'Germany': (357114, 83783942)} countries_dict["Brazil"] = (8515767, 212559417) countries_dict["India"] = (3166391, 1380004385) # for loop for i in countries_dict.keys(): print("Country name:", i) print("Area:", countries_dict[i][0]) print("Population:", countries_dict[i][1]) print("---------")
There key was country name and respective value - is a tuple with area and population. You see, that this for loop is much "friendlier" than the previous ones.
