Reassigning 'Hello' in this nested list to say 'Goodbye'

[mcdermottbobby]

list3 = [1,2,[3,4,'hello']]

I know the solution to this is: list3[2][2]='goodbye'

Why is this the solution? I don't understand why that is the answer and would appreciate an explanation, thank you!

list3[2] is the third item in the list, which is itself a list of 3 items.

list3[2][2] is the third item in the list of the third item in the list.

Thank you! Much clearer now
