Get enumeration name by value [duplicate]

Are there any standard methods to get Enumeration names by value?

An example:

class Example(enum.Enum):
    one = 1
    two = 2

ex_variable = 1

Given ex_variable, can I obtain the string contained in Example.one.name?

>>> Example(1).name
'one'

also see the Python docs.

To access the members of enums programatically:

>>> Example(ex_variable).name
'one'
