Question

In Python, write a program that uses a class to represents a spaceship. A spaceship has some amount of jets, landing gear, parachutes and astronauts. It must leave Earth’s gravity, so it must use all its jets to propel itself off Earth. The spaceship will spend some time exploring before returning to Earth. When it returns to Earth, it will use its parachute and landing gear to land safely. Make sure that those are extended before landing!

Sample output:        Your spaceship has 5 astronauts, 2 jets, stored landing gear and parachute.

The spaceship is taking off!

Your spaceship is exploring...

Your spaceship is heading back to Earth.

Oh no! You’re landing gear and parachute weren’t extended! The expedition ended in failure.

Sample output:        Your spaceship has 10 astronauts, 4 jets, stored landing gear and parachute.

The spaceship is taking off!

Your spaceship is exploring...

Your spaceship is heading back to Earth.

The landing gear and parachute have been extended!

Your ship has arrived safely back on Earth.

Thanks for the question.

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change.If you are satisfied with the solution, please rate the answer.

======================================================================================

class SpaceShip():
    
    # marking the gear and parachutes as optional with default values as False
    def __init__(self,astronauts,jets,gear=False,parachutes=False):
        self.__astronauts=astronauts
        self.__jets=jets
        self.__gear=gear
        self.__parachutes=parachutes
    # getter functions
    def getAstronauntsCount(self):
        return self.__astronauts
    def getJetsCount(self):
        return self.__jets
    def getGear(self):
        return self.__gear
    def getParachutes(self):
        return self.__parachutes

# takes in a SpaceShip object and simulate the launching of spaceship, explortion and return to earth
def goOnMission(spaceship):
    print('Your spaceship has {0} astronaunts, {1} gets, stored landing gear and parachute'.\
          format(spaceship.getAstronauntsCount(),spaceship.getJetsCount()))
    print('The spaceship is taking off!')
    print('Your spaceship is exploring...')
    print('Your spaceship is heading back to Earth.')
    if spaceship.getGear() is not True or spaceship.getParachutes() is not True:
        print('Oh no! You’re landing gear and parachute weren’t extended! The expedition ended in failure.')
    else:
        print('The landing gear and parachute have been extended! Your ship has arrived safely back on Earth.')


def main():
    # don t pass the value of gear and parachutes, it will default to False
    spaceX = SpaceShip(5,2)
    #  pass the value of gear and parachutes as True
    spaceY=SpaceShip(10,4,True,True)
    goOnMission(spaceX)
    print()
    goOnMission(spaceY)

main()
