Funny Quiz Questions

Question

I was taking a Python quiz, and I came upon this question:
‘What is the output of this code?
ppap = [“pen”, “pineapple”, “apple”, “pen”]
print(len(ppap))
The answer was not 4.

Answer 1

Adding on to what @Sebastián Zapata said;

There is no error with the question. However, I notice you have made a mistake while writing the question; this is the corrected question:

ppap = {"pen", "pineapple", "apple", "pen"} #Note the curly brackets
print(len(ppap))

As ppap is a set, it does not accept repeated values. (So the second "pen" is omitted). Hence the length is 3. If it were square brackets "[]" and not curly ones (like your original question), it would be 4.

Answer 2

Maybe there was a detail that you didn't see. The result of that is really 4.
If you use set: " { } ", the result is 3 because it doesn't accept repetitions. But in lists " [ ] ", as you writed the quiz the answer must be 4.

Answer 3

hm... report the question with "wrong answer"

Answer 4

if ur question over here is exactly the same u had then, 4 is the length.
but if it's { } it's considered as set, and set doesn't allow repetition so 'pen' is taken as one and length is 3

Answer 5

Yeah... I was sure it was square brackets, but I must have been mistaken.
