Hello everyone,

just learned about the .remove method. However, if I wanted to remove an item in a list in relation to its index, how do I go about this?
…considering the fact that .remove does not accept any parameter, other than the actual item to be removed.


You could use the del statement- https://docs.python.org/3/tutorial/datastructures.html#the-del-statement, del lst[index]

Oh, thank you. This is extra, and very useful. I later found what I was looking for.

The .pop method. We can remove an item in a list in relation to it’s index. But your response taught me something new, and I appreciate!


Hi everyone,
is there a method to remove more than one item at a time?


with the code :

new_store_order_list = [“Orange”, “Apple”, “Mango”, “Broccoli”, “Mango”]

how come it only removes one of the "Mango"s and not both? And how does it decide to remove the Mango in index 2 or the Mango in index 4?


That’s just the way it’s designed to work, if you check the docs it gives a brief description-

Remove the first item from the list whose value is equal to x


Thank you! In that case, how would you go about removing all the Mangos in the list? Is the only way to use a “for” loop to look for every mango in the list?

In truth if the list was not referenced elsewhere (and didn’t consume an absurd amount of memory) I’d prefer to create a new list skipping all the values that equal ‘mango’, so-

new_store_order_list = [
    for element in new_store_order_list
    if element != 'mango'

The problem with removing multiple values is that the length of the list changes when you remove them, so iterating through that list becomes quite difficult. I think a single pass noting the index of each matching element and then removing them in reverse might be a passable option. Sounds like an interesting task if you wanted to give it a shot :slightly_smiling_face:.

Wow thank you so much!


Just went and completed “Shrinking a List: Remove” and there was no requirement to iterate over the list. We use only the .remove() method to remove “Flatbread” and then later, “Mango”, and attempt to remove “Onions” to see the KeyError that gets raised.

I like the del statement better.
I also found .pop() to delete by index.

you can use del statement like take a example code:

my_list = ['medicine', 'groceries', 'snacks', 'toys']
      # if i want to remove snacks cause im getting fatty so i can:
del my_list[2]
#in output my snacks will be removed :(

del - it means like Delete?

The link in that message would give you more information(it also links again to more info) than I can reply with but yes it’s a contraction of delete.

So today, I found two exciting ways to remove an index.

del new_store_order_list[-1]

I think .pop is my favorite.

Hi everyone, quick question:
For the exercise provide to remove “Mango”, why did it choose to remove the middle position “Mango” instead of the Mango at the last index? Is there a hidden rule behind it?

Thanks for answering!

How come the remove() doesn’t remove both “Chris” indexes in the example?

Is there a way to remove all indexes of a particular string, boolean, int, or float, at the same time?

Also, I do not know how to copy and paste from the example like I’ve seen others do. I tried to do it here and part of my message was formatted as a header and it didn’t look right. How do we copy and paste the example exercises? Thanks!
