字典和类

Question

我有这段代码：

class weapon():
    def __init__(self, Name, Type, Description):
        self.Name=Name
        self.Type=Type
        self.Description=Description

WEAPONS = { "starterSword":weapon("Starter Sword", "Sword", "A short, stunt steel sword."),
        "basicSword":weapon("Basic Sword", "Sword", "A basic steel sword.")
        }

我想做这样的事情：

for item in WEAPONS:
    print(self.Name)

我将如何在Python 3中进行此操作？

Answer 1

迭代values：

for item in WEAPONS.values():
    print(item.Name)

Answer 2

正如@MSeifert所说。无论如何，迭代字典为您提供每个项目的关键和价值。所以这也有效：

for key, value in WEAPONS.items():
    print(value.Name)

顺便问一下：你为什么要用字典？因为每个武器都有自己的名字。

Answer 3

最好在类中编写方法（OOP）并调用它们而不必编写大量代码，例如。

class weapon():
    def __init__(self, Name, Type, Description):
        self.Name=Name
        self.Type=Type
        self.Description=Description
    def printDetails(self):
        print (self.Name)

WEAPONS = { "starterSword":weapon("Starter Sword", "Sword", "A short, stunt steel sword.").printDetails(),
        "basicSword":weapon("Basic Sword", "Sword", "A basic steel sword.").printDetails()
        }

将为您提供所需的输出。
