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.
Convert int to Enum using Enum.Use the Enum. ToObject() method to convert integers to enum members, as shown below.
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
