Refactor core.transforms.generate_transforms() for ease of reading#148
Merged
Conversation
Now it no longer captures variables from the generate_transforms() function, so we should be ready to move it up to the module level.
I've made this private since it's intended for module use only.
…elections() Pass arguments into the function instead of capturing them from the environment.

Makes sense to me. If the helper functions rely on state from the enclosing scope or it's not clear if they can be victims of side-effects or cause side-effects, they need to be improved. Making them into pure (or more pure) private functions makes is a good move.

Closes #141.
This PR refactors the
core.transforms.generate_transforms()function by pulling out several functions defined within this larger function. The previous format with nested functions was difficult to read becausegenerate_transforms()was several hundred lines long and because some of the nested functions closed over variables ingenerate_transforms(). After the refactor, some of the functions are still pretty long, but the module is much more navigable than before.I've pulled the nested functions out as private functions in the
core.transformsmodule. The public API of this module should not change at all with this change, and there shouldn't be any functionality changes either.During the refactor, I also discovered the
skipattribute which is available to all feature selection transforms. I added some tests for it and added it to the documentation.
