Comments posted to this topic are about the item Python division

Correct answer:

-20

Explanation:

The // operator is an integer division operator. In this case, the result of the division is converted to an integer, as the floor of the integer. That is 21 in this case.

correct answer = -20, yet the explanation states 21?

Tsk, tsk...

Just because you're right doesn't mean everybody else is wrong.

Tried an online Python compiler and it also returned -21, so I guess -21 is the correct answer.

"The // operator is an integer division operator" that's false (-20). It's a FLOOR division (-21).

If the question had been "81 // 4" it would have been 20, but "-81 // 4" is -21...

Can we get this point back? Petty perhaps, but still...

You got more points by typing a response than the question is worth.

All replies agreed that the correct answer should be -21 (because one of the operands is negative). In this case, can we get our point back for today's breakfast? 🙂

You did by posting. Honestly, points are rather....well...pointless. They are also super easy to earn. Just start answering forum questions.
