Implement __copy__ and __deepcopy__ methods for HexCode

[mezarque]

Overview

When trying to use HexCode objects in plotly (not currently supported), we can run into problems caused by the way that plotly handles color objects; namely, that it uses deepcopy at some point in the figure generation process to create a copy of an input color object. Because of the way we developed HexCode to inherit from str, we don't currently override the __copy__ or __deepcopy__ methods. My guess is that this results in a problem when deepcopy is used on a HexCode object.

Example

Example Plotly code that causes an error:

import plotly.express as px

import arcadia_pycolor as apc

x = [1, 2, 3, 4, 5]
y = [1, 2, 3, 4, 5]
c = ['A', 'B', 'A', 'A', 'B']

cmap = {
    'A': apc.teal,
    'B': apc.tangerine,
}

px.scatter(x, y, color = c, color_discrete_map=cmap)

Solution

For now, users can use the .hex_code property of a HexCode object to circumvent this limitation of our implementation. In the long term, we should consider implementing overrides of __copy__ and __deepcopy__ into HexCode to more easily support plotly.

Some validation that this is the reason:

from copy import deepcopy

deepcopy(apc.teal)
