如何通过变量检索Enum键

I'm new to python. Is it possible to get the value of an Enum key from a variable key?

我新到python。是否可以从变量键获取枚举键的值?

class Numbering(Enum):
 a=2
 b=3

key=b
print(Numbering.key)
#the result I want is 3

One of the many neat features of Python's Enums is retrieval by name:

在Python的枚举中，有一个很简洁的特性就是检索名称:

>>> print(Numbering[k])
Numbering.b

and for the value:

和值:

>>> print(Numbering[k].value)
3
