While loop & continue

I want to get the result of: [5, 4, 2, 1] with the code below, but the code keep running without showing the result

start = 5
list = [ ]
while start:
    if start == 3:
       continue #
   list.append(start)
   start -= 1

print(list)

However if i use break, i can get a result: [5, 4] with the code below.

start = 5
list = [ ]
while start:
   if start == 3:
      break #
   list.append(start)
   start -= 1

please advise if there is a way for me to achieve [5, 4, 2, 1] with while loop or another other way

thank you

I found work around!!! But i still dont know why the continue doesn't work

start = 5
list = [ ]
while start:
    if start != 3:
        list.append(start)
    start -= 1

print(list)

Jeffrey,

You're very close. There are several ways to do this, of course, but remember that even if the number is 3, you still want to decrement the count before returning to the top of the while loop. So:

start = 5
list = [ ]

while start:
   if start == 3:
       start -= 1
       continue
   list.append(start)
   start -= 1

print(list)
