I'm trying to use a while loop instead of a for loop. How would I change this code so that it works using a while loop in python?

Question

# Generating Hollow Pyramid Pattern Using Stars

row = int(input('Enter number of rows required: '))

for i in range(row):
    for j in range(row-i):
        print(' ', end='') # printing space required and staying in same line

    for j in range(2*i+1):
        if j==0 or j==2*i or i==row-1:
            print('*',end='')
        else:
            print(' ', end='')
    print() # printing new line

I've tried swapping the (for) for (while <= .... etc) and add in i = 1 and i += 1 at the end but none seem to work.

Based on the code above, are you sure that you are adding the integer increment within the while loop?

for example,

i = 1
while i <= 10:
  do_something
  i+=1

will stop after 10 cycles, but

i = 1
while i <= 10:
  do_something
i+=1

will go on forever
