list

Question

number = 3
things = ["string", 0, [1, 2, number], 4.56]
print(things[1])
print(things[2])
print(things[2][2])

How does this last code works?

Answer 1

things[2] = [1,2,number]
so
things[2][2] = [1,2,number][2] = number = 3

Answer 2

things is a list and has a list in it at index 2. The element at index 2 of this list in things is indexed in the last line of your code
