Why cannot I capture the ctrl+C key (KeyBoardInterrupt exception of python) in external terminal of VS Code?

I use VS Code to develop python program. And I found it cannot capture the ctrl+C key when using the external terminal, but it worked properly with the integrated terminal.

Here is my python code:

import time

print('press enter to start,and press ctrl+C to stop:')
while True:

    input("")
    starttime = time.time()
    print('Started')
    try:
        while True:
            print('Counting:', round(time.time() - starttime, 3), 'seconds',end='\r')
            time.sleep(0.001)
    except KeyboardInterrupt:
        print('\nEnd')
        endtime = time.time()
        print('Total Time:', round(endtime - starttime, 3), 'seconds')
        break

and here is my lauch.json file with integrated terminal:

{
    "stopOnEntry": false,
    "configurations": [
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        }
    ]
}

here is my lauch.json file with external terminal:

{
    "stopOnEntry": false,
    "configurations": [
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "externalTerminal"
        }
    ]
}

With the external terminal, the code cannot stop when I give it a ctrl+C key. I want to figure out why and how to fix this. Thank you for helping.

Using Keyboard interrupts to close your program isn't a great way but if you still want to I think it is ctr + alt + m for VS code. To do it the proper way you should use the keyboard module:

import keyboard

if keyboard.is_pressed('q'):
    print('goodbye')
    quit()

As mentioned in the comments, OP wants an error to be excepted in which case just use

raise Exception('Exiting')

In the code:

import keyboard

if keyboard.is_pressed('q'):
    print('goodbye')
    raise Exception('Exiting')

This can caught by:

except Exiting:
    print("Key Board Interupt")
