What is the difference between sys.stdin.readline() and input()?

Question

Python

I was sorting out the problem, and I stumbled upon
N = int(sys.stdin.readline())
What is bad about the usual one int(input())?
Task just in case link to task . Task at the end

Answer 1

What's wrong with regular int(input()) ?

Nothing. These are slightly different things, since input() takes a prompt string that must be printed before accepting a response - it's like print() + sys.stdin.readline().
In the context of the task, there is no difference.
