Why is this 7 and not 8

Question

Nums = [9, 8, 7, 6, 5]
Nums.append(4)
Nums.Insert(2,11)
Print(len(nums))
Answer 7 . I don’t understand why it’s 7 and not 8. Do we not count the append if insert is after it?

Answer 1

The reason is that the insert() function takes two parameters:
index - position where an element needs to be inserted, and
element - this is the element to be inserted in the list.
So you start with 5 elements, then you append one, so now you have 6 elements, and then insert one at index position 2, so now you have 7 elements, i.e. len(nums) is 7.
By the way, you would get an error with the code as you have written it ("nums is not defined") because the first 3 times you refer to your list you use "Nums" and the last time, you use "nums" and Python is case-sensitive. (I'm guessing it's your keyboard auto-capitalizing first letters of first words)

Answer 2

The 2 is not added Brandon Carpenter . That's just the index or location where the 11 is inserted.

Answer 3

[9, 8, 7, 6, 5] has a length of 5 elements, you append a 4 so now it has a length of 6 elements, now you insert 11 so the list now has a length of 7 elements

Answer 4

ohps thank you for pointing that out the capital was auto correct but i didnt realize that regardless! but thank both of you i understand now that makes sense!

Answer 5

nums =[9,8,7,6,5]
nums.append(4)
append function is used to add the Element at the end of the list.
Now...
Element 4 will be added at he end of the list.
nums ={9,8,7,6,5,4}
nums.Insert(2,11)
insert(index,element)
insert is a function which takes 2 parameters .
index-at which position the element is to be inserted.
Element-which element u have to insert into the list.
At the second position the element will be inserted
nums =[9,8,11,7,6,5,4]
Print (len(nums))
"len" is a function which is used to know the length of the list.
Length of a list is "7".
nums =[9,8,11,7,6,5,4]
1 2 3 4 5 6 7
Answer = "7"

Answer 6

Jake but theres a 2 do we not count that?
