Python Collections - Lists Redux: Removing List Items Quiz

Here's the problem:

my_list = [1,2,3,4]

I want to delete the 4 from my my_list using del.

_______________ my_list[ _____________ ]

The underscores signify answer fields. My goal is to submit

del(my_list[my_list.index(4)])

but I cannot add the closing parenthesis for the del function. Is there another syntax that I am missing? Thanks!

Why are you looking up the index? You can see the list. Just delete that index.

Yes of course! So with the fill-in-the-blank style questions, there is no need to use parenthesis? Thanks

It'll depend on the question. On this one, I just wanted to make sure you could count indexes correctly and use the del keyword with a list.

my_list = [1, 4, 2, 3] I want to delete the 4 my from my_list using del.

This has no answer

It totally has an answer. You delete items from a list using del by using the index. What index is the 4 at?
