1. class Moon

2. earthWeight

3. moonWeight = earthWeight/6

4. def setMoonWeight(ew):

5. if ew != 0:

6. earthWeight = ew

7. self.moonWeight = ew/6

8. def getMoonWeight(self):

9. return self.moonWeight

10. def main():

11. earth = float(input("What is the weight of earth: ")

12. Moon lunar

13. setMoonWeight(earth)

14. print("The weight of earth lunar is ", getMoonWeight() )
