identity-containers 1.1.0

Introduction

This module implements dicts and sets that compare items based on identity rather than value. This allows them to store unhashable objects.

Usage example:

from identity_containers import IdentitySet

foo = []
bar = []

id_set = IdentitySet([foo])

print(foo in id_set)  # True
print(bar in id_set)  # False

The following classes exist:

• IdentitySet
• IdentityDict
• IdentityDefaultDict
• IdentityWeakKeyDict
