Python: passing flags to functions

Question

For a long time i have been trying to figure out what is the best way to pass flags to python functions. The most straightforward way is something like:

def func         


        

Answer 1

What about flipping it over?

flag1, flag2, flag3, flag4, flag5, flag6 = range(6)

def func(enable=[], disable=[],
         enabled_by_default=[flag5, flag6]):
    enabled = set(enabled_by_default + enabled) - set(disabled)
    if flag1 in enabled:
        ...
    if flag2 in enabled:
        ...

func(enable = [flag1, flag2, flag3],
     disable = [flag6])
