Hello,
I am trying to remove some items from a list using .remove(). However, I get an error stating that... (see the following code and error).
new_list = [1, 6, 7, 8];
new_list.remove([7, 8]);
print(new_list);
Traceback (most recent call last):
line 28, in <module>
new_list.remove([7, 8]);
ValueError: list.remove(x): x not in list
Thanks!

Your code will work if new_list was [1, 2, 3, 4, 5, 6, [7, 8]], i.e having a list of [7, 8] as an element in the list. You should remove 7 and 8 individually.
