for loop (3/5)

After the last task, you can see that it looks good, but it would be much better if we could also get both numbers separately. This is possible, as you can put one loop in another.

For example, you surely remember our list with 5 countries and their areas and populations. Firstly, we can build for loop to print each element. Then, we can check, if this element is a tuple. If True, we need to iterate over its elements. To check if the object is, for example, tuple, use

object is tuple

Let's see how it works:


              1234567891011
            
# countries data
countries = ['USA', (9629091, 331002651), 'Canada', (9984670, 37742154), 
             'Germany', (357114, 83783942), 'Brazil', (8515767, 212559417), 
             'India', (3166391, 1380004385)]

for i in countries: # iterate over list
  if type(i) is tuple: # check if it is tuple
    for j in i: # if tuple, then iterate over it
      print(j)
  else: # if not, just print item
    print(i)
