How do I convert an int to enum in Python?

Use parenthesis to convert an integer to an enum in Python, e.g. print(Sizes(1)) . You can pass the integer value of an enum member as an argument to the class and it will return the enum member. Copied! The Sizes(1) syntax allows us to pass an integer to the class and get the corresponding enum member.

How do I convert an int to enum?

What is Auto () in Python?

With the help of enum. auto() method, we can get the assigned integer value automatically by just using enum. auto() method. Syntax : enum.auto() Automatically assign the integer value to the values of enum class attributes.


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>

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
