Print v Return video - Day 10

[liamoc89]

During this video, when calculating the second answer, you use the following code:

second_answer = calculation_function(calculation_function(num_1, num_2), num_3)

print(f"{first_answer} {operator} {num_3} = {second_answer}")

When you ran this code, your first calculation was 3 + 2 = 5, then you used 5 and chose the * operator to multiply by num_3, which you chose as 3.
The printed f-string displayed 5 * 3 = 18 in the console, which is obviously incorrect.

After running through the code on pythontutor.com, it appears as though when calculating the second answer, you're changing the operator so the calculation_function(num_1, num_2) part of the second_answer, actually multiplies the first 2 numbers together, before carrying out the same calculation with num_3.

i.e - 3*2 = 6, then using 6 as the value of calculation_function(num_1, num_2)

If you're using the same operator both times, there won't be an issue here, however, it seems better just to use
second_answer = calculation_function(first_answer, num_3)
