Introduction

This module provides extensions to dicts in the python standard library, providing fast and clean manipulation of nested dictionary structures. This module exposes two new dict-types:

• NestedDict/ndict: A light-weight wrapper for dict s that provides additional functionality for operations on nested dictionary structures.

• StructuredNestedDict/sndict: A heavy-weight data dict -based structure for operating on hierarchical data with rich functionality for filtering and transformation across nested levels.

Both implementations are use OrderedDict s under the hood.

No additional dependencies are required.

Features

• NestedDict/ndict:

  • Iterating over flattened keys and values

  • Nested getting/setting operations

  • Applicable to dictionaries of arbitrary and unbalanced depth

• StructuredNestedDict/sndict:

  • flatten/stratify/rearrange methods allow for powerful and rich operations across different levels of hierarchy

  • Nested getting/setting operations, including intelligent filtering via ix

  • Convenient data inspection via dim, unique_keys, etc
