Set of tools for comparing complex objects
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.
Currently one may expect issues with sets and Decimal
.
