[Python] match/case statement in python does not allow use of list item as the case [duplicate]

I have an os dependent program and I wanted to use a match/case statement and function to match a key input to its corresponding value. I have the "values" for each os stored in different tuples and I was hoping to use these as the cases by doing something like this (but in a class):

import os
import CONTROLS # File with ASCII values

# UP DOWN RIGHT LEFT
if os.name == "posix":
CONTROL_CODES = range(65, 69)
else:
CONTROL_CODES = (72, 80, 77, 75)

pressed = None
def _input_control_codes(char):
global pressed
match char:
case CONTROL_CODES[0]: # UP
pressed = CONTROLS.UP
return
case CONTROL_CODES[1]: # DOWN
pressed = CONTROLS.DOWN
return
case CONTROL_CODES[2]: # RIGHT
pressed = CONTROLS.RIGHT
return
case CONTROL_CODES[3]: # LEFT
pressed = CONTROLS.LEFT
return

_input_control_codes(65) # example
print(pressed)


The above yields the error message:

File "~/main.py", line 14
case CONTROL_CODES[0]: # UP
^
SyntaxError: invalid syntax



I was wondering if there was a way to accomplish this without having to use an if statement or manually writing 2 match/case statements?
