[issue9636] {'key': 'value'}[b'key'] raises a BytesWarning

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

Oh. flox told me that there are other cases raising BytesWarning:

'abc' in {b'abc'}
'abc' in (b'xxx',)
'abc' in [b'xxx']

I suppose that the behaviour is different (only fail with same value / fail with different values) because set does first compare the hash (as dict), whereas tuple and list use a classic comparaison.
