elif confirm == 'yes':
                print(classes[0])
                chosenClass = classes[0]
                break

这总是选择与所选类相同的索引（Knight）。
另外，使用csv.DictReader可以清除所有令人困惑的索引符号。

def ClassPicker():
    print('Select Your Class')
    with open('data.csv', 'r') as classes:
        classes = list(csv.DictReader(classes))
        while True:
            for i, row in enumerate(classes, 1):
                class_name = row['Class']
                print(f'[{i}]{class_name}')
            inspect = int(input('')) - 1
            for key, val in classes[inspect].items():
                print(f'{key}: {val}')
            print('Are You Sure You Want To Select This Class')
            print('[yes] [no]')
            confirm = input('').lower()
            if confirm == 'no':
                print('Select Your Class')
            elif confirm == 'yes':
                print(classes[inspect])
                chosenClass = classes[inspect]
                break
            else:
                print('Enter A Valid Option')

        # One Time Class Stat Setting
        Character.role = chosenClass['Class']
        Character.health = chosenClass['Health']
        Character.physicalDamage = chosenClass['Physical Damage']
        Character.rangedDamage = chosenClass['Ranged Damage']
        Character.magicDamage = chosenClass['Magic Damage']
        Character.defense = chosenClass['Defense']

问题出在线路上：

print(f'{classStats[classes[inspect].index(x)]}: {x}')

注意你的数据， Mage 的物理伤害和远程伤害是一样的（都是5）。因此，程序运行classes[inspect].index(5)两次，这将打印Physical Damage两次。
我的修复意见是替换这段代码：

for x in classes[inspect]:
    if classes[inspect].index(x) >= 2:
        print(f'{classStats[classes[inspect].index(x)]}: {x}')
    else:
        print(x)

用zip函数创建一个简单的dict：

for k, v in dict(zip(classStats, classes[inspect])).items():
    if k in ("Class", "Description"):
        print(v)
    else:
        print(f"{k}: {v}")

它应该会打印出你想要的东西。

这听起来像一个有趣的项目！在Python中，你做的一些事情有点不合常规。例如，修改Character类的类变量而不是creating an instance of that class.。我尝试重构你的代码，使其更像Pythonic。
我已经将逻辑分离成更小的函数，我们现在使用csv.DictReader，并且我们正在示例化一个新的Character()，而不是修改类本身。
作为进一步的增强，您可以检查dataclass是否适合您的角色。
