How to write a program which simulates a rocket launch countdown and then displays a rocket and launches it through the top of the screen?

To create a rocket launch countdown simulation, you can use a programming language like Python with a library such as Pygame. First, implement a countdown timer that displays numbers from 10 to 1 with a brief pause between each number. Once the countdown reaches zero, render a rocket image on the screen and animate its movement upwards by gradually decreasing its vertical position in a loop until it exits the top of the screen. Ensure to include event handling to allow for starting and stopping the simulation as needed.
