for loop (4/5)

Let's make our output a bit user-friendlier. Last time we iterated over all elements. Now let's iterate over indexes, and get elements by their indexes. For example, for countries, considering we know that each country is represented by two numbers, it will look like:

12345678910111213
# countries data countries = ['USA', (9629091, 331002651), 'Canada', (9984670, 37742154), 'Germany', (357114, 83783942), 'Brazil', (8515767, 212559417), 'India', (3166391, 1380004385)] # construct user-friendlier for loop for i in range(len(countries)): # it will iterate over all indexes if type(countries[i]) is tuple: # check if our element is tuple print('Area:', countries[i][0], 'sq km') print('Population:', countries[i][1]) print('--------------') else: print('Country name:', countries[i])
copy

There we used knowledge about our data, that each tuple is the length of 2. Also, we added a dotted line after each tuple to divide countries.
