Is the answer to this question valid? as >>> a [3] is supposed to be = 4

Question

Please note that the sign ( « ) isn't originally in the code, it is, to specify my interest.

QUESTION:
Fill in the gap to print Hello world !
a = [ 1, 2, 3, 4]
a [ ] « = 2
If 4 in a :
Print( "Hello world !")
else:
Print("Goodbye world")

ANSWER:
a = [ 1, 2, 3, 4]
a [ 3 ] « = 2
If 4 in a :
Print( "Hello world !")
else:
Print("Goodbye world")

I thought that if we wanted to know the position of [3] in the list, we should use a.index(3) instead .
Pls anyone? Explain this. Maybe i'm wrong on my part, i need to understand .

Answer 1

Ok thanks a lot~ swim ~
This isn't the only question like this, I've been losing challenges because of this, and i prefer understanding the question to learning it the way it is.

Answer 2

That's exactly what I'm complaining about. The output should be "Hello world !" , but 4 in a is replaced as 2 because a [3] = 2. So it will print "Goodbye world" instead, this question should be removed from the py quiz or corrected, such that the question will state: Fill in the gap to print "Goodbye world" instead of "Hello world"

Answer 3

I didn't
I was just checking through correct answers after a challenge, and i saw 3 in empty space as the answer
left for me i'll put 1 in the empty space
