How to convert a nested python dictionary into a simple namespace?

Let's say I have a nested dictionary with depth N. How can I convert each inner nested dictionary into a simple namespace?

example_input = {key0a: "test", key0b: {key1a: {key2a: {...keyNx}, key2b: "test"} ,key1b: "test"}}example_output = SimpleNamespace(key0a: "test", key0b: SimpleNamespace(key1a: SimpleNamespace(key2a: SimpleNamespace(...keyNx), key2b: "test"), key1b: "test"))

Are there better alternatives to make the keys of the dictionary accessible per dot notation (e.g. example_input.key0a) if the example_input dict is given - without having external dependencies?
