Question

我有这个密码：

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.")
        }

我想这样做：

for item in WEAPONS:
    print(self.Name)

在python3中我该如何做呢？你知道吗

Answer 1

正如@MSeifert所说。不管怎样，遍历字典会为每个项提供键和值。所以这也是可行的：

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

顺便问一下：你为什么用字典？因为每种武器都有自己的名字。你知道吗

Answer 2

只需迭代values：

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

Answer 3

最好是在类（OOP）中编写方法并调用它们，而不必编写大量代码

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()
        }

会给你想要的输出。你知道吗
