Solve the following python programming problem given the following code:
# %load asyncio_cancel_task2.py
import asyncio

async def task_func():
    print('in task_func, sleeping')
    try:
        await asyncio.sleep(1)
    except asyncio.CancelledError:
        print('task_func was canceled')
        raise
    return 'the result'

def task_canceller(t):
    print('in task_canceller')
    t.cancel()
    print('canceled the task')

async def main(loop):
    print('creating task')
    task = loop.create_task(task_func())
    loop.call_soon(task_canceller, task)
    try:
        await task
    except asyncio.CancelledError:
        print('main() also sees task as canceled')

event_loop = asyncio.get_event_loop()
try:
    event_loop.run_until_complete(main(event_loop))
finally:
    event_loop.close()

!python asyncio_cancel_task2.py
Given the above code, generate some markdown instructions for it.

#Here is the Python program you requested.

This example creates and then cancels a task before starting the event loop. The result is a CancelledError exception from run_until_complete().
If a task is canceled while it is waiting for another concurrent operation, the task is notified of its cancellation by having a CancelledError exception raised at the point where it is waiting.
