Just as lists can be nested within lists or tuples within tuples, loops can also be nested to iterate over elements inside other loops. For example, when working with a list that contains multiple sublists, a nested loop can iterate through both the main list and its inner elements.


              
1234567891011121314

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


# Iterate over list
for country in countries: 
    
    # Iterate over nested list
    for j in country:
        print(j, end = ' ')
      
    print('\n') # Print new line after nested loop finish
copy

The variable j represents each element within the nested lists inside the countries list. As the inner loop iterates, j sequentially takes on the values of each element in the sublists, printing them one by one.
