Type annotations?

Also, Python 3.6 is end of life in 3 weeks, so it might simplify annotations to use Python 3.7 features immediately.

[Marco-Sulla]

@NeilGirdhar It seems to me that type annotations works with frozendict. Now from python 3.9+ you can also write frozendict[type, type].

+1 for deepfreeze (#30).

I need to determine if list items are unique, i.e. if len([a, b, c]) == len(set([a, b, c])) where a, b, c can be anything including nested dicts.

a = [{'x': 1}, {'y': 2}, {'x': 3}, 'foo', 4]
b = [{'x': 1}, {'y': 2}, {'x': 1}, 'foo', 4]
c = [{'x': 1}, {'y': {'y2': 2}}, {'x': 1}, 'foo', 4]

b2 = [frozendict(x) if isinstance(x, dict) else x for x in b]
c2 = [frozendict(x) if isinstance(x, dict) else x for x in c]

print(len(b2))
print(len(set(b2)))     # works
print(len(set(c2)))     # fails

Since a hashable/frozen dict isn't already part of standard Python for some reason, thank you so much for creating it, and TIA for making it deep.

To be honest, I already implemented it:

The problem is I would add a way to register your own mutable type with a callable that makes it immutable. And tests. A lot of tests.
