Explore Nested Loops in Python
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.
# 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
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.
