Python Python Basics (Retired) Shopping List Shopping List Project

Same output, without Continue. Why ?

print ('Write something to the list !')
print ('When your done, write: Done')

shoppingList = []
#newItem = input ('Write: ')

while True:
    newItem = input ('Write: ')

    if newItem == 'Done':

    print ('Added ! List has {} items.'.format(len(shoppingList)))

print ('This is your list: ')
for stuff in shoppingList:
    print (stuff)

Because the loop is going to continue anyway. The continue is unnecessary but I included it to point out where the loop restarts.

When I was trying it for first time, I made that commented statement on line 5. Of course, under while line was just newItem.

So, when it was this way, keyword continue, didn't fix an infinite loop which I made.

P.s.: How do I make text, bold, italic please ?

continue can't fix an infinite loop because it just causes the loop to move on to the next step. If there is an infinite number of steps, continue will happily just keep on moving.

Under ever comment box there's a link for the Markdown Cheatsheet. That'll show you how to do formatting in your comments/posts.
