Python Loops Tutorial

If/Else in a Nested Loop

Utilizing if statements remains consistent whether applied within nested loops or in a single while or for loop.

Examine the code below:


              123456789101112131415161718
            
matrix = [[1, -4, 4, 29],
     [3, 4, -200, -1],
     [10, -5, 0, 8]]

# Changing negative numbers to 'N'
i = 0
#  Setting outer while loop to work with the number of rows 
while i < len(matrix):
  j = 0
  #  Setting inner while loop to work with the number of elements in the row
  while j < len(matrix[i]):
    if matrix[i][j] > 0:
      print(matrix[i][j], end = ' ')
    else:
      print('N', end = ' ')
    j +=1
  i += 1
  print('')

How does the code work?

We've just observed an example of utilizing if/else within a nested loop while handling the matrix.

Now, in your assignment, you'll be dealing with two strings.

Feel free to refer to hints if necessary!

Tarea

Print all the vowels from the text.

Initialize i.
Configure the outer while loop to iterate through the number of elements in the text.
Configure the inner for loop to iterate through the number of elements in the vowels.
Implement the condition: if an element in the text matches one of the elements in vowels, then print the element.
