python - 在python中将枚举转换为int

Question

我有一个枚举国籍:

class Nationality:
        Poland='PL'
        Germany='DE'
        France='FR'

如何以这种或类似的方式将一些枚举转换为 int:

position_of_enum = int(Nationality.Poland)  # here I want to get 0

我知道如果我有代码，我可以做到:

counter=0
for member in dir(Nationality):
    if getattr(Nationality, member) == code:
        lookFor = member
        counter += 1
return counter

但我没有，而且这种方式对于 python 来说看起来太大了。我确信还有更简单的方法。

请使用IntEnum

from enum import IntEnum

class loggertype(IntEnum):
    Info = 0
    Warning = 1
    Error = 2
    Fatal = 3

int(loggertype.Info)
0
