in control strutcures at list functions 3rd question why is it 7? please answer

Answer 1

len is a function that returns the length of an iterable.

Initially the list has 5 elements.

Then one element is appended.

Then another element is inserted (the following elements all move one spot to the right).

So now there are 7 elements in that list.
