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])

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.

Using the same approach as in the example, print the information about all people from the people list.
