The only difference is that the copy() method of frozendict takes Coax is a modular Reinforcement Learning (RL) python package for solving OpenAI Gym environments with JAX-based function approximators. If no parameters are passed to frozenset() function then it returns a empty frozenset type object. Example: >>> class Classic: ... pass ... >>> Classic.attr=1 >>> class FinalizedType: ... __final__=True ... >>> FinalizedType.attr=1 (...) TypeError: 'frozendict' object does not support item assignment This patch is not part of the PEP 416 … Plug-n-play Reinforcement Learning in Python with OpenAI Gym and JAX. The only difference is that the copy () method of frozendict takes variable keyword arguments, which will be present as key/value pairs in the new, immutable copy.

The frozenset() is an inbuilt function is Python which takes an iterable object as input and makes them immutable. It can be used as a drop-in replacement for So, we will use a feature called as frozendict in python. A persistent data structure is defined as a data structure that preserves the previous version of the data when the data is modified. Such data structures are effectively immutable, as operations on them do not update the structure in-place, but instead always yield a new updated structure (see [0]_ for more details.) Some features may not work without JavaScript. generate link and share the link here.
