The Other Key Features in What’s New In Python 3.10 contains the following code snippet:
from enum import Enum
class Color(Enum):
RED = 0
GREEN = 1
BLUE = 2
match color:
case Color.RED:
print("I see red!")
case Color.GREEN:
print("Grass is green")
case Color.BLUE:
print("I'm feeling the blues :(")
However, the variable color is unknown, hence, NameError: name 'color' is not defined is shown. The solution is the declare a color variable and assign it any of the Color enum values, like so:
from enum import Enum
class Color(Enum):
RED = 0
GREEN = 1
BLUE = 2
color = Color.BLUE
match color:
case Color.RED:
print("I see red!")
case Color.GREEN:
print("Grass is green")
case Color.BLUE:
print("I'm feeling the blues :(")
