N3 - Mistake

Question

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

Result:
>>>
0
[1, 2, 3]
3
>>>
things[2][2] is number not 3 :)))

Answer 1

number is a variable. number = 3. when the print statement evaluates the variable number, it prints 3, so 3 is correct.

if your list were as follows: things = ["string", 0, [1, 2, 'number'], 4.56]

then the output would be 'number'. If you are interested, try running this code in the code playground, IDLE or a python interpreter. Step through the code as it is running and inspect the variables. That will help you see what is going on.

Answer 2

3 it's correct since you've assigned that value to the number variable
