Installation

objectmapper requires Python >= 3.6 because it relies on modern type annotations. ::

pip install objectmapper

Example

import objectmapper mapper = objectmapper.ObjectMapper()

One-to-one mappings

def int_to_str(i: int) -> str: ... return str(i) mapper.create_map(int, str, int_to_str) mapper.map(42, str) '42'

Many-to-one mappings

def int_float_to_str(i: int, f: float) -> str: ... return str(i + f) mapper.create_map((int, float), str, int_float_to_str) mapper.map((42, 42.5), str) '84.5'
