Data Hiding
We are working on a game. Our Player class has name and private _lives attributes.
The hit() method should decrease the lives of the player by 1. In case the lives equal to 0, it should output "Game Over".
Complete the hit() method to make the program work as expected.
class Player:
def __init__(self, name, lives):
self.name = name
self._lives = lives
def hit(self):
#your code goes here
if self._lives == 0:
print('Game Over')
else:
return self._lives-=1
p = Player("Cyberpunk77", 4)
p.hit()
p.hit()
p.hit()
File "<ipython-input-298-8696dd8489ab>", line 11
return int(self._lives)-=1
^
SyntaxError: invalid syntax
You should not return decreased lives. Even if you need it, Python interpreter sees it as invalid syntax; then you need to do decreasing of/assigning to _lives and returning it as different statements.
Hint: the problem is in `return self._lives-=1`.
Thank you so much.
Now I got the answer
here is the correct answer:
class Player:
def __init__(self, name, lives):
self.name = name
self._lives = lives
def hit(self):
self._lives -= 1
if self._lives == 0:
print('Game Over')
#your code goes here
p = Player("Cyberpunk77", 3)
p.hit()
p.hit()
p.hit()
