input interrupt

[Gribouillis]

Here is a solution I wrote two years ago. I hope it helps

import selectors
import sys
 
def main():
    sel = selectors.DefaultSelector()
    sel.register(sys.stdin, selectors.EVENT_READ)
    print("Enter passcode: ", end='')
    sys.stdout.flush()
    pairs = sel.select(timeout=5)
    if pairs:
        passcode = sys.stdin.readline().strip()
        print('you entered:', passcode)
    else:
        print('\ntimed out')
 
if __name__ == '__main__':
    main()
