Colander is a serialization / deserialization / validation library for strings, mappings and lists. It is useful as a system for validating and deserializing data obtained via XML, JSON, an HTML form post or any other equally simple data serialization.
Colander is tested on Python 2.7, 3.5, 3.6, 3.7, and 3.8, and PyPy and PyPy3.
This is free and open source software.
Key Features
- Define a data schema.
- Deserialize a data structure composed of strings, mappings, and lists into an arbitrary Python structure after validating the data structure against a data schema.
- Serialize an arbitrary Python structure to a data structure composed of strings, mappings, and lists.
- Serialize and deserialize various types of objects, including:
- A mapping object (e.g. dictionary).
- A variable-length sequence of objects (each object is of the same type).
- A fixed-length tuple of objects (each object is of a different type).
- A string or Unicode object.
- An integer.
- A float.
- A decimal float.
- A boolean.
- An importable Python object (to a dotted Python object path).
- A Python datetime.datetime object.
- A Python datetime.date object.
- A Python enum.Enum object.
