Using exceptions in python to transport values without explicit dependencies

exception_tricks.py

# define in some util somewhere
class MyException(Exception):
    class A:
        value = 4

# raise an exception with a custom value to be caught elsewhere
def myfunc(b):
    a = MyException
    a.value = b
    raise a

# catch the exception and get the value in another part of the code
try:
    myfunc(6)
except MyException as e:
    print(f"Got {e.__class__.__name__} with value: {e.value}")
