bookFirst Nested Loop Pattern

A nested loop is a loop located within the body of an outer loop. Either the inner or outer loop can take on various forms, including a while loop or a for loop. For instance, the outer for loop can encompass a while loop, and conversely.

Initially, let's attempt to create a basic image using a nested loop.

Employ end = ' ' within the print function to display elements in a row.

Examine the code below:


              
1234567

            
# Printing a triangle
# Outer for loop
for i in range(1, 5):
  # Inner for loop
  for j in range(1, i + 1):
    print('*', end=' ')
  print('')
copy

How does the code work?

Tarea

You should reverse the triangle shown in the example.

  1. Configure the range() function for the outer for loop with step = -1.
  2. Configure the range() function for the inner for loop.
  3. Print '*' within the nested loop.
