Immutable wrapper around dictionaries (a fork of frozendict)
Project description
immutabledict
A fork of frozendict, an immutable wrapper around dictionaries.
It implements the complete mapping interface and can be used as a drop-in replacement for dictionaries where immutability is desired. The immutabledict constructor mimics dict, and all of the expected interfaces (iter, len, repr, hash, getitem) are provided. Note that an immutabledict does not guarantee the immutability of its values, so the utility of hash method is restricted by usage.
The only difference is that the copy() method of immutable takes variable keyword arguments, which will be present as key/value pairs in the new, immutable copy.
Installation
Available as immutabledict
on :
- pypi
- conda-forge (community-maintained, not an official release)
Example
from immutabledict import immutabledict my_item = immutabledict({"a": "value", "b": "other_value"}) print(my_item["a"]) # Print "value"
