How to intercept ctrl + c command in python running in cygwin

I run python script inside a cygwin shell but I'm not able to intercept ctrl + c command.

This is my python script:

#!/cygdrive/c/python27/python.exe -u
import signal
import sys
def signal_handler(sig, frame):
    print('You pressed Ctrl+C!')
    sys.exit(0)

signal.signal(signal.SIGINT, signal_handler)
signal.signal(signal.SIGTERM, signal_handler)
signal.signal(signal.SIGBREAK, signal_handler)

print('Press Ctrl+C')
input()

Also using a try/catch method still not working

#!/cygdrive/c/python27/python.exe -u
try:
    input()
except KeyboardInterrupt:
    print('Interrupted')

but non of these handler works with ctrl + c command. The Cygwin version is 1.7.25(0.270/5/3) and I'm using python 2.7. What's wrong?

I have the same problem in the MSYS environment (https://www.msys2.org/) in its mingw64 terminal. I was finally able to fix the issue using the winpty tool:

winpty python3 my_python_script.py

This way signal handlers work as expected. I'm just not sure if the winpty tool is available in your cygwin distribution as well.
