dotwiz

DotWiz is a Python library providing a dict subclass that allows attribute-style (dot) access to keys, including automatically transformed nested dict and list values. Instead of writing my_dict['this']['dict']['has'][0]['nested']['data'], users can write dw.this.dict.has[0].nested.data. Installation is via pip install dotwiz. The main DotWiz class accepts a dict plus optional keyword arguments, and offers to_dict() to convert back to a plain dict. A helper make_dot_wiz() builds an instance from an iterable of key-value pairs, allowing keys that are not valid Python identifiers to still be accessed through bracket notation. DotWizPlus extends this by converting special-cased keys (spaces, mixed case, leading digits, reserved keywords, or names colliding with dict methods such as items, get, or values) into safe snake_case attribute names. Original keys remain accessible via dict-style access, and to_attr_dict() returns the sanitized attribute form. The README claims performance advantages over alternatives such as dataclasses.make_dataclass, prodict, Box, and DotMap, with benchmark details in the documentation. The project is documented on Read the Docs, tested via GitHub Actions and Codecov, and accepts contributions through pull requests and issues.
