Why in python data types are returned differently based on the way ENUM declared?

Question

from requests import delete, get, post, put
from enum import Enum

class HTTPMethod(Enum):
       """HTTP methods allowed."""
       GET = (True,get)
       PUT = (False,put)
       POST = (True,post)
       DELETE = (False,delete)
    
    
>> data = HTTPMethod.GET

>> type(data)
Returns : <enum 'HTTPMethod'>

The datatype returned in the above one is enum but When the Enum is declared as mentioned below the data type returned is a function. Any idea why is it this way ??

from requests import delete, get, post, put
from enum import Enum

class HTTPMethod(Enum):
       """HTTP methods allowed."""
       GET = get
       PUT = put
       POST = post
       DELETE = delete
    
    
>> data = HTTPMethod.GET

>> type(data)
Returns : function
