reprlib now abbreviates frozendict by item, using the maxdict limit:

>>> reprlib.repr(frozendict({i: i for i in range(10)}))
'frozendict({0: 0, 1: 1, 2: 2, 3: 3, ...})'

Previously: 'frozendict({0..., 8: 8, 9: 9})'.

  • Issue: Many pure python tools that have a special cases for dict should accept frozendict as well. #145056

Sorry, something went wrong.

feat(pythongh-145056): Support frozendict in reprlib
8d84daa 
- Add Repr.repr_frozendict() sharing _repr_mapping() with repr_dict()
- frozendict reprs were cut in the middle instead of abbreviated by item
- Register frozendict in Repr._lookup so shadowed names are not matched
