In Python, how do I make my program automatically exit after 5 minutes?

Question

I am making a text adventure code for my computer science class. The player is in a school setting, trying to figure out who the murderer is. I have not finished the code yet, but there will be only one correct ending where the player finds the murderer and the game can be replayed as many times as the player wants. I want to set a time limit on my game, so the player only has 5 minutes to find the correct way to the murderer. How do I do that? Is there a module that I should download? This is my code:

school_map = """This is the map of your school.

|______ ______|_______ _____|______ ______|

|-------   ---------|                     |
|                   |---------   ---------|
|     cafeteria     |                     |

|   locker rooms                          |

Answer 1

Use the alarm signal to trigger a handler that exits your program.

import sys
import signal


def alarm_handler(signum, frame):
    sys.exit("Times up!")


signal.signal(signal.SIGALRM, alarm_handler)
signal.alarm(5*60)
