So in the session it gives the example for adding one item to a list by using this code:

my_list + [4]

but when I did that to try it out it didn’t work. I had to type:

my_list = my_list + [4]

and then it would print the list + 4 the other way didn’t throw a code but it didn’t add 4 to the end of my list. Is it not suppose to?

Ok to add, I tried it in terminal, since we set up IPython and I wrote this code:

list = [1, 2, 3, 4, 5]

list + [4]

the first print statement printed “[1, 2, 3, 4, 5]”
the second printed “[1, 2, 3, 4, 5, 4]”

So it does work that way! However it doesn’t print that way in the codecademy playground.


Hi, I’m having trouble with running the code in this lesson. It runs but the exercise still says I’ve done it incorrectly despite the “hint” indicating that I have done it correctly. Is there an issue with Codecademy Pro or am I missing something? My code is:

orders = [“daisy”, “buttercup”, “snapdragon”, “gardenia”, “lily”]

Create new orders here:

new_orders = orders + [“lilac”, “iris”]

Don’t worry. I figured it out. I didn’t realise the exercise was wanting me to create two separate lists.


Yeah, this one threw me for a little while too - for anyone else confused, this guy is right :slight_smile:

I’m still confused. I might need a more explicit answer, please. Thank you.

UPDATE: figured it out. Just declare a new list called new_orders with lilac and iris as list items.
