File "/tmp/45847549d9de27aa1265/file.py", line 28 grid=[list(map(int, input().split())) for_in range(N)] ^SyntaxError: invalid syntax
Solution
The error is due to a typo in your list comprehension. The keyword for is separated from the variable in by an underscore, which is causing the syntax error. The correct syntax for list comprehension in Python is:
grid = [list(map(int, input().split())) for _ in range(N)]
Here, I've used an underscore (_) as the variable, which is a common convention in Python when the variable is not going to be used in the loop. If you plan to use the variable, you should give it a name, like this:
grid = [list(map(int, input().split())) for i in range(N)]
In this case, i would be the variable that takes on each value in the range from 0 to N-1.
