我如何修复我的代码，以便它可以 print() 输出我想要的结果？
How Do I Fix My Code So It Can print() Out The Results I Want?
注意：我不是要你重新编写我的代码，我是在寻找可以帮助我改进此代码的提示和站点链接。如果你想修复代码，我也会接受你的答案。
我正在尝试了解 class 的工作原理，但我真的很难理解。我制作了一个名为 Stat 的 class，其中包含给定用户的所有统计信息。用户的所有统计数据为 name, level, totexp and role。每个 role 有 3 个统计数据（它应该有三个，但是，我的代码搞砸了），health, attack, and defense。这是主要代码（不工作）：
class Stat():
def __init__(self, name, level, totexp, role, health, attack, defense):
self.name = Name
self.level = 1
self.totexp = 0
self.role = Role
self.health = health
self.attack = attack
self.defense = defense
self.exp = 0
def choose_name():
while(True):
Name = input("What is your Dicer's name?:\n").title()
if(any(Bad_Words in Name.lower() for Bad_Words in [])):
print("That's an inappropriate name! Try again")
elif(len(Name) < 3):
print("That name is too short! Try again.")
elif(len(Name) > 16):
print("That name is too long! Try again.")
else:
break
def choose_role():
Roles = {
'mage':lambda:Role(100, 40, 10), #(Health, Attack, Defense)
'warrior':lambda:Role(100, 30, 20),
'gunner':lambda:Role(100, 20, 30),
'archer':lambda:Role(100, 10, 40)
}
while(True):
Role = input("What role do you want to be?\nChoices:\n1. Mage\n"
"2. Warrior\n3. Gunner\n4. Archer\n").title()
if(Role.lower() in (Roles)):
return
else:
print("That's not a role! Try again.")
self = choose_name()
self = choose_role()
在主代码之后 Results（如标题）或结果代码应该 print 出 Stats 根据实例的顺序。这是结果代码：
print("Here is your Dicer's information:\nDicer's name: {0}\n"
"Level: {1}\nExperience: {2}\nRole: {3}\nRole Stats:\n"
"Health: {4}\nAttack: {5}\nDefense: {6}".format(self.name, self.level,
self.totexp, self.role,
self.health, self.attack,
self.defense))
当我 运行 代码时出现错误：
Traceback (most recent call last):
File "python", line 37, in <module>
AttributeError: 'NoneType' object has no attribute 'name'
我想我知道为什么会发生这种情况，但我不知道如何解决它。你能帮我从哪里开始我的代码和修复它的方法吗？这是我想要的结果（对于此示例，名称 = Bob 和角色 = Gunner）：
Dicer's name: Bob
Level: 1
Experience: 0
Role: Gunner
Role Stats:
Health: 100
Attack: 20
Defense: 30
我对 post 有点犹豫，因为代码一团糟。但是你说你不想重写你只是想看到你的代码被修复，所以这里是固定的。我已经评论了我更改的所有内容
