The program alarm.py pops up a user-specified message after 2 minutes. The message can be any piece of text, and is displayed calling the (ficticious) function alert(). When the user types alarm.py Switch off your laptop, write a program that calls alert('Switch off your laptop', seconds=120).
We want to allow the user to specify how many seconds later the alarm should be set. So, for example, if we type:
```
  alarm.py --seconds=30 Hello
```
... change the program to call alert('Hello', seconds=30). If --seconds is not specified, it sets --seconds to 120 seconds.
The user may want the alarm to be specified at multiple times. So, if we type:
```
  alarm.py --seconds=10 --seconds=20 Hello
```
... change the program to call alert('Hello', seconds=10) followed by alert('Hello', seconds=20).
