这是一个错误,还是我? [英] Is this a bug, or is it me?
问题描述
大家好,
出于某种原因,以下情况不起作用:
C级:
TYPES = [无]
DICT = {}
类型为类型:
DICT.update([E]中的E的(E,类型))
>> NameError:全局名称''Type''未定义
您怎么看?这是一个错误吗?

大家好,
由于某种原因,以下方法不起作用:
class C:
TYPES = [无]
DICT = {}
输入类型:
DICT.update((E,在[1]中输入E)
> NameError:全局名称''Type''未定义

不要使用这些名字......选择真的很差......
thingydingy = [无]
my = {}
for thingydingy:
my.update([(E,dingaling)for E in [1]])br />
打印我的

你不能在它的类声明
范围内访问类的类变量,因为类型的名称在完成课程
声明之后才受约束。
尝试:
C级:
TYPES = [无]
DICT = {}
类型为C.TYPES:
C.DICT.update((E,Type)for E in [1])

Arrgh!我讨厌制作它的错误。但是我想补充一点,Python的类声明的这个
属性只有在我认为它才会让我困扰
将使用类变量作为默认方法参数
值。幸运的是,我不经常想。 ;)

Hello all,
For some reason, the following does not work :
class C:
TYPES = [None]
DICT = {}
for Type in TYPES:
DICT.update((E,Type) for E in [1])
>>NameError: global name ''Type'' is not defined
What do you think? Is this a bug?

What do you think? Is this a bug?Do not use those names...really poor choice...
thingydingy = [None]
my = {}
for dingaling in thingydingy:
my.update([(E,dingaling ) for E in [1]])
print my

What do you think? Is this a bug?You cannot access a class''s class variables in it''s class-statement
scope, since the name of the type is not bound until after the class
statement is completed.
Try:
class C:
TYPES = [None]
DICT = {}
for Type in C.TYPES:
C.DICT.update((E, Type) for E in [1])

property of Python''s class statement bothers me only when I think it
would be good to use class variables as default method argument
values. Luckily, I don''t think very often. ;)
