Is this code right? If not, How can we correct its syntax?

Question

s='think'
s= ".join(sorted(list(s)[:4]))
print(s)

Answer 1

'' on line 2 is two single quotes instead of one double quote.

Answer 2

I took this code from a challenge question proposed by @Demeth. I've already signaled another wrong question. I want to know if moderators have ability to delete questions which syntax are false.

Answer 3

Thank you Hatsy Rei. Demeth has just corrected is question.
