Explore Nested Loops in Python
Just as you can nest lists within lists or tuples within tuples, you can also loop through elements that are already being looped over. For example, you can loop through a list that contains other lists.
1234567891011# 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
Note
In this code,
jrepresents each element within the nested lists inside thecountrieslist. As the nested loop iterates,jtakes on the values of each element in the inner lists, which are then printed.
