bookWhile Loop inside a for Loop

Using one type of loop within another is a commonly employed technique.

Today, we'll explore utilizing a while loop within a for loop. You can accomplish the same task by employing a for loop within a while loop.

Examine the code below:


              
1234567891011

            
names = ['Anna', 'Richard', 'John', 'Patrick']

# Printing every name for 3 times
# Setting outer for loop to work with names
for i in names:
  j = 0
  # Setting inner while loop to work with the number of name's printing
  while j < 3:
    print(i, end = ' ')
    j += 1
  print('')
copy

How does the code work?

Tarefa

Print the string matrix using a while loop nested within a for loop.

  1. Configure the outer for loop to iterate through the number of rows in the matrix, using the variable i.
  2. Initialize the variable j.
  3. Configure the inner while loop to iterate through the number of elements in each row of the matrix, using the variable j.
  4. Display each element within the nested loop.
  5. Increment the variable j.
