Magically import magic number constants. Like so:
from magic_numbers import FORTY_TWO, SIXTY_NINE, FOUR_HUNDRED_AND_TWENTY
from magic_numbers import ONE_THOUSAND_THREE_HUNDRED_AND_TWELVE
from magic_numbers import THREE_POINT_ONE_FOUR_ONE_FIVE_NINE_TWO as PI
from magic_numbers import NEGATIVE_SIX_HUNDRED_AND_SIXTY_SIX
from magic_numbers import MINUS_ZERO_POINT_ONE
print(f"{FORTY_TWO = }") # 42
print(f"{SIXTY_NINE = }") # 69
print(f"{FOUR_HUNDRED_AND_TWENTY = }") # 420
print(f"{ONE_THOUSAND_THREE_HUNDRED_AND_TWELVE = }") # 1312
print(f"{PI = }") # 3.141592
print(f"{NEGATIVE_SIX_HUNDRED_AND_SIXTY_SIX = }") # -666
print(f"{MINUS_ZERO_POINT_ONE = }"
6DA4
) # -0.1Note: Floats can only be specified using "point", there is no support (yet) for fractions like THREE_AND_A_HALF or TWO_THIRDS
