Catching SIGINT with conditional exit in Python -

-

i want catch sigint signal in python script. however, script should terminate if user enters correct password after sending sigint. can done in python? sample code illustrate problem:

import signal  def signal_handler(signal, frame):     password = raw_input("enter password: ")     if password != "secret":         print("wrong password!")         # todo don't let process end     else:         print("password correct. exiting now.")  signal.signal(signal.sigint, signal_handler)

edit: changed variable 'pass' 'password', suggested in comments below.

you can capture sigint , dispatch call off function.

e.g. 

import signal import sys import time  def confirm_password(signal, frame, secret="shhh"):   password = raw_input("enter password: ")    if password == secret:       sys.exit(0)   else:       print("password incorrect.  refusing exit.")  while true:     signal.signal(signal.sigint, confirm_password)     time.sleep(1000)

edit add code i've verified work, not example memory :)
