immutabledict


An immutable wrapper around dictionaries. immutabledict implements the complete mapping interface and can be used as a drop-in replacement for dictionaries where immutability is desired.
It's a fork of slezica's frozendict. This library is a pure Python, MIT-licensed alternative to the new LGPL-3.0 licensed frozendict.
