Request to use polars dataframe package directly

[jnhyeon]

Thank you for creating a great package.
polars is a next-generation high-performance dataframe package that will replace pandas.
After converting polars to pandas using to_pandas(), you can use the feature-engine package.
However, it would be even better if you could directly process polars dataframe in the feature-engine package!

Have a nice week :)

Hey @jnhyeon

I agree with you: adding support for polars is a much needed improvement.

It's also a major undertaking because Feature-engine was designed with pandas in mind, so most of its functionality is based on pandas.

I'll need to get myself familiar with polars first, to get a clear view of the workload needed, or find someone with expertise that could take this forward.

So in principle, I agree, in practice, I am not sure how soon we can move forward with this.

Comparing the number of monthly downloads of pandas and polars, I think pandas is here to stay for the foreseeable future as well.
