How to convert int to Enum in python?

I think it is in simple words is to convert the int value into Enum by calling EnumType(int_value), after that access the name of the Enum object:

my_fruit_from_int = Fruit(5) #convert to int
fruit_name = my_fruit_from_int.name #get the name
print(fruit_name) #Orange will be printed here

Or as a function:

def convert_int_to_fruit(int_value):
    try:
        my_fruit_from_int = Fruit(int_value)
        return my_fruit_from_int.name
    except:
        return None

You 'call' the Enum class:

Fruit(5)

to turn 5 into Fruit.Orange:

>>> from enum import Enum
>>> class Fruit(Enum):
...     Apple = 4
...     Orange = 5
...     Pear = 6
... 
>>> Fruit(5)
<Fruit.Orange: 5>

From the Programmatic access to enumeration members and their attributes section of the documentation:

Sometimes it’s useful to access members in enumerations programmatically (i.e. situations where Color.red won’t do because the exact color is not known at program-writing time). Enum allows such access:

>>> Color(1)
<Color.red: 1>
>>> Color(3)
<Color.blue: 3>

In a related note: to map a string value containing the name of an enum member, use subscription:

>>> s = 'Apple'
>>> Fruit[s]
<Fruit.Apple: 4>
