Python 3 KeyboardInterrupt error

I have noticed that on any python 3 program no matter how basic it is if you press CTRL c it will crash the program for example:

test=input("Say hello")
if test=="hello":
    print("Hello!")
else:
    print("I don't know what to reply I am a basic program without meaning :(")

If you press CTRL c the error will be KeyboardInterrupt is there anyway of stopping this from crashing the program?

The reason I want to do this is because I like to make my programs error proof, and whenever I want to paste something into the input and I accidentally press CTRL c I have to go through my program again..Which is just very annoying.

Control-C will raise a KeyboardInterrupt no matter how much you don't want it to. However, you can pretty easily handle the error, for example, if you wanted to require the user to hit control-c twice in order to quit while getting input you could do something like:

def user_input(prompt):
    try:
        return input(prompt)
    except KeyboardInterrupt:
        print("press control-c again to quit")
    return input(prompt) #let it raise if it happens again

Or to force the user to enter something no matter how many times they use Control-C you could do something like:

def upset_users_while_getting_input(prompt):
    while True: # broken by return
        try:
            return input(prompt)
        except KeyboardInterrupt:
            print("you are not allowed to quit right now")

Although I would not recommend the second since someone who uses the shortcut would quickly get annoyed at your program.
