one small gripe i have is that the repr¹ doesn’t handle aliases (ie items with more than one bit set) that well , but tbh its not an easy problem

example to illustrate the problem :

class Foo(enum.Flag):
    A = auto()
    B = auto()
    C = auto()
    # no D
    AB = 0b0011
    CD = 0b1100

print(Foo.AB | Foo.C)  # <Foo.A|B|C: 7> NOT <Foo.AB|C: 7>
print(Foo.CD | Foo.A)  # <Foo.A|C|CD: 13> NOT <Foo.A|CD: 7>

its a minor thing but it annoys me a bit

[1]: the _name_ member , which is used by __repr__ , of an enum member is actually generated either when the individual enum class is created or when the value is first needed by _missing_ . also the docs call these names surrounded by single underscores “sunder” names

while many great things have been said in this thread i’ll also link to the docs for enum.Flag (docs.python.org) which wraps bitmap integer enums
