Convert string to Enum in Python

I wonder what's the correct way of converting (deserializing) a string to a Python's Enum class. Seems like getattr(YourEnumType, str) does the job, but I'm not sure if it's safe enough.

Just to be more specific, I would like to convert a 'debug'string to an Enum object like this:

    class BuildType(Enum):
        debug = 200
        release = 400

This functionality is already built in to Enum [1]:

    >>> from enum import Enum
    >>> class Build(Enum):
    ...   debug = 200
    ...   build = 400
    >>> Build['debug']
    <Build.debug: 200>
