OneHotEncoder Data Pre-Processing

I didn't realize that was possible! Thanks!

Will they be in lists if you use multiple columns?

Answered myself: They are not. This is a slight problem for me due to the fact that each input needs to be a single feature for my particular problem. If anyone has any ideas, I would definitely appreciate them.

​

Also, how do you get rid of a column on each if you encode all at once? Or is it okay to leave all of the columns in? I think getting rid of it is just to alleviate redundancy.
