equator 0.0.1

Set of tools for comparing complex objects

Set of tools for comparing complex objects

Quickstart

equator is available on PyPI and can be installed with pip.

$ pip install equator

After installing equator you can use it like any other Python module.

Here is a simple example:

from equator import equals

item1 = [
    {
        1: [
            {1: [1, 2]},
            [1, 2.0001],
        ],
    },
    [3, [4, [5]]],
]

item2 = [
    {
        1: [
            {1.0001: [1, 2.0001]},
            [1.0001, 1.9999],
        ],
    },
    [2.9999, [4, [5.002]]],
]

result = equals.approx(item1, item2, rel_tol=1e-2)
assert result

The function approx allows one to compare approximately objects of various types.

The motivation to create this function was that pytest.approx does not allow comparison of the complex objects. In contrast, this function allows one iterate through __dict__ of arbitrary objects and make use of math.isclose when encountering numeric types.

TODO

Currently one may expect issues with sets and Decimal.
