使用類內的return語句從類中獲取值

Question

class Player1: 
    base_HP = 300 

    def getBHP(self): 
     return self.base_HP 


jogador1 = Player1 
jogador1_hp = jogador1.getBHP() #Functions and Class calls must end with brackets. 


print(jogador1_hp) 

這就是我用來獲取播放器HP的代碼，我想將它保存在jogador1_hp中。

如何過這是IAM越來越：

C:\Users\joaol\AppData\Local\Programs\Python\Python36-32\python.exe C:/Users/joaol/PycharmProjects/FirstProgram/Main.py 
<function Player1.getBHP at 0x02C131E0> 

Process finished with exit code 0 

即使我下面做，我仍然得到一個空白控制檯。編輯：我修復它，我只需要添加「（）」，當我創建對象！

jogador1 = Player1() 
jogador1_hp = jogador1.getBHP() 

Answer 1

您必須調用方法才能執行它們。

jogador1_hp = jogador1.getBHP() 

Answer 2

如果我使用jogador1_hp = jogador1.getBHP（）我得到這個：

C:\Users\joaol\AppData\Local\Programs\Python\Python36-32\python.exe C:/Users/joaol/PycharmProjects/FirstProgram/Main.py 
Traceback (most recent call last): 
    File "C:/Users/joaol/PycharmProjects/FirstProgram/Main.py", line 19, in <module> 
    jogador1_hp = jogador1.getBHP() 
TypeError: getBHP() missing 1 required positional argument: 'self' 

Process finished with exit code 1 

Answer 3

你不實例化Player1類。在您的代碼中，jogador1只是Player1類的另一個名稱。你應該叫這個類來實例化它，例如：jogador1 = Player1()
